As the saying goes, "it is difficult to draw a hand when drawing a person."
When studying the opponent in painting, we should not only study its modeling structure, but also study the relationship between its actions and characters. Because of the long-term cooperation between hand and brain, hand movements can transmit emotional information. Its emotional expression is not as easy to control as facial expression, but a natural expression. This can better explain the important role of hands in expressing characters' personalities.
The hand consists of 8 carpal bones, 5 long metacarpals and 14 closely arranged phalanges. The whole hand has 27 bones, 16 joints.
The muscles of the hand include adductor pollicis, thumb to palm, flexor pollicis brevis, first interosseous reserve muscle, palmar bone muscle, little finger to palm muscle, abductor digiti minimi muscle, palmar brevis muscle, palmar longus tendon, dorsal interosseous muscle and extensor digitorum communis tendon.
There is a great difference between the palm surface and the back of the hand, and the action of fingers is mainly to bend into the palm. The palmar surface of the hand has three parts: thenar, thenar and palmar mound, and the palm is between the three parts. The dorsal metacarpal is a whole with an outer arc, and radial metacarpal bones and obviously distributed blood vessels can be seen on the surface.
There are three factors in the decent performance of hands, namely, bones, muscles and wrinkles. These three factors are intertwined, but their respective characteristics are obvious. We should judge them when performing and draw their characteristics in different ways. For example, thin and hard lines can be used to represent bones; thick and soft lines can be used to represent muscles; Wrinkles can be represented by lighter and weaker lines.
For the performance of the finger, it should be noted that it is a cylinder 168, and the structure and texture changes on it should conform to the perspective law of the cylinder.
Nails are also part of the hand. Fingernail has a certain radian, and its four sides are connected with fingers in different ways. The inside is buried under the skin, the two sides are embedded in the fingers, and the outside is the cross section of the nail. When painting, you should use different expressions.
The wrist performance of the hand is also very important. Eight small bones of the wrist are wrapped in ligaments to form an arch. The unique shape of the wrist is always a "bridge" connecting the palm and forearm. One end of the carpal bone is connected with the radius of the forearm to form a wrist joint. The wrist joint is very flexible, which can make the hand flex, bend sideways and swing. Hand movements are usually triggered by the wrist. If you ignore the subtle changes in your wrist, you will lose the vitality and vitality of your hand. In addition, an obvious feature of the wrist is the styloid process at the lower end of ulna and radius, which combines with the adduction wrists on both sides of the wrist to form two obvious bone points, which is a feature of wrist modeling.
People's hands are the same as people's faces, and their personalities are very different, which is caused by age and gender. There are also reasons for professional experience, as well as geographical and ethnic reasons. They are divided into wide and thin, thick and thin in form; There are differences between tension and relaxation, toughness and weakness in action.
The hand is the part that needs to be portrayed in the sketch of the bust. Methods of characterization: First, fully express the contrast factors such as modeling, structure, dignity, light and shade, lines and so on. The other is to make it stand out by using the contrast of background. The relationship between the head and the hand, because of their long distance, is usually not the main treatment. In some cases, the performance of the left hand and the right hand should distinguish between primary and secondary relations, for example, the near hand is more specific and the far hand is more rough. In short, in the sketch of bust, the hands and head should be regarded as the rhythm factors in the painting, forming a relationship of mutual echo, contrast, change and unity.

Sketch how to draw a structured hand
First observe the hand posture to see if it is natural and beautiful, and whether the model can maintain this posture for a long time.
All these conditions are met, and the next step is to conceive the picture, the hand and how to express it, and then quickly summarize the shape of the hand with a long line after knowing it. The structure of the hand is very complicated, showing many ups and downs. At this step, you don't have to care too much about the details. Find out the big pieces of the hand, separate the big pieces of black, white and gray, grasp the transition between the blocks, and properly depict the details of the hand in the transition part, such as the joint bone points of the fingers.
When appropriate, you can rub your hands to make the tone of the dark side look gentle, breathable and integrated, and also make the space in the dark feel farther away. The effect of wiping with a pen is different from that of wiping with your fingers. Relatively speaking, the tone of rubbing by hand will be easier.
In order to strengthen the understanding of hand structure, the depiction of hand in sketch bust is another key object besides head. Hand performance can fully reflect the character's action characteristics and inner spiritual activities, and it is also the second window of the soul.
However, due to the similar appearance of fingers, many changes and great age differences, the performance of hands is particularly difficult. As the saying goes, it is difficult to draw a horse, but it is difficult to draw a hand.
This step is the focus of characterization, that is, the visual center of the whole hand map is there, and that is the focus of characterization. This gesture focuses on the index finger and middle finger joints.
When describing these wonderful places, you should change pencils and draw more. When describing a joint, we should pay attention to the fact that it is a bump, and find out the dark side and gray side of the bump. The little tunes here should be painted neatly, so that the picture will be wonderful.
The joint bone point is connected with the tendon, and the tendon of the back of the hand gradually extends from the lower part of the wrist and separates to the five fingers. Finally, look at whether the description of the hand is complete, and see where it is not keeping up and where it is too tight. At this time, it is necessary to supplement the incomplete parts of the picture to make the picture tight and loose, harmonious and unified.
Sketcher's hair painting
Structure of hand
Hand bones include eight carpals, five metacarpals and fourteen phalanges, wherein the carpals are located at the wrist of the hand and arranged in two rows with four bones in each row. Metacarpal bone is a kind of small tubular bone, which is distributed between phalanx and wrist bone and arranged in a fan shape. The phalanx is also a small tubular skeleton. Except the thumb, the other four fingers each have three knuckles. Hand muscles are divided into three parts: lateral group, medial group and middle group. The lateral group is located under the thumb, forming a raised part on the palm, and the medial group is located under the little finger, slightly raised. The middle group is located in the palm, with vermiform muscle and interosseous muscle.
Hand-drawn sketch
When sketching and sketching hands, the first thing to do is to understand the structure of the hand, and it is easier for opponents to sketch on this basis. Let's introduce the sketcher's painting method in several steps.
The first step is to gently draw the general structure, shape and dynamics of the hand with a straight line on the prepared sketch paper. This step should be light, so that the drawn line can be easily modified.
The second step is to find out the specific shape and structure of the hand. When sketching in this step, we must combine the structural relationship of the hand we have mastered (as mentioned above) to describe the large structure and shape, and we must draw it accurately.
The third step is to draw a big relationship between light and shade on the already drawn picture, and summarize it when drawing, and don't portray the dark side particularly delicately.
The fourth step is to describe the opponent in depth and detail. This link is mainly about drawing the gray and dark reflection of the hand. The pen should be light and can be painted several times, so that the hand shape drawn will have better visual effect. Such as Mona Lisa by leonardo da vinci and Portrait of a Lady Holding Flowers by Zhou Fang in Tang Dynasty, clearly show the charm of the characters.
How to draw a stick figure with great gestures
Material preparation: pencil, eraser, paper 1 First, write four sixes side by side on the paper to ensure that the sizes of the four sixes are basically the same.
2. Then turn the paper counterclockwise and fill the gap between 6 with lines. 3. Then, outside the circle below the number 6, draw the fingertip shape of the finger in turn.
4. Finally, draw the thumb, and the prototype of the whole hand is basically drawn. 5. Draw a nail for your thumb, line it up, and you will draw a thumbs-up hand.
Extended data:
Note: 1. Pay attention to the radian when drawing the outline of your thumb. 2, draw the rest of the curved four fingers, four fingers pay attention to have a sense of hierarchy.
3. You don't need deep painting skills to draw stick figures, you can master them with a little practice.
What is the gesture of holding a pen in sketch?
First, the pen holding skills
1. Take a shape with a large outline, and hold the pen when drawing roughly light and dark.
Palm up, thumb and forefinger holding the pencil. Generally, the thumb presses the pencil at the first internal joint of the index finger, with the nib facing outward and the little finger supported on the drawing board as the fulcrum. You can also put your little finger away and hang it directly. Painting is done by swinging and moving your wrist!
2. In-depth description, the way to hold a pen when describing details in depth is similar to writing. The thumb and forefinger hold the nib at the first joint of the middle finger, with the nib facing down. Painting is done through the cooperation of fingers and wrists.
Second, the placement of the drawing board.
1. When the painter sits upright, the position of the drawing board should be 90 degrees perpendicular to the realization of the eyes. The sketchpad should keep a distance from the painter, so that the painter can straighten his elbow, so that he can always take into account the overall situation in the process of painting and prevent the perspective error caused by the perspective!
2. Try not to move the sketchpad after the position is fixed, so as not to affect the perspective change of the picture during the sketch process!
