Skills and techniques of facial sketch.

First, painting skills:

1, from the perspective of large volume?

Facial features and hair are important manifestations of the head, but these local factors must be subordinate to and attached to the large volume of the head, and the relationship between them must always be paid attention to. The head modeling must pay special attention to several bone points that cause a decent turning point: parietal tubercle, frontal mound, eyebrow arch, cheekbone and mental tubercle.

2. Dynamic and perspective?

The accurate grasp of head immobility depends on the correct understanding of its visual angle change. Eyebrow arch, nasal arch and cleft palate can be regarded as three horizontal lines. Eyebrow center, human nasal tip and mandible can be regarded as the central axis perpendicular to these horizontal lines, which together constitute the dynamic line of the head. We can observe and grasp the dynamic characteristics through their perspective changes in motion.

3. Attitude and personality characteristics?

Manner and personality characteristics are the spiritual content of incarnation. To make it correct and vivid, we must first rely on and understand the form, that is, "to write the spirit with form, to be rich with form, and to have both form and spirit." Grasping the form depends on keen intuition.

4. What is the texture of each part?

Different from plaster head, different parts of a real person's head have different textures, such as silky hair; The nose, especially the alar, is waxy; There are wrinkles in the mouth and thin cortex. These parts are easy to produce highlights because of their bright texture. Keenly feeling and expressing the texture features of each part will make the picture more concrete and vivid.

5. facial features?

The five senses are an important part of the head and the key content to grasp the characters. ?

Eyes: Generally speaking, eyes are the core of a character's demeanor, including eyes, eyelids and eyeballs. The overall shape of the eye can be understood as a sphere embedded in the concave frame. ?

Nose: It is divided into nose bridge and nose head, and its overall shape can be summarized as a trapezoid cube. The nose is the key to grasp the shape of the nose and the most complicated part of the body. It consists of nose, alar, nasal septum and nostril. ?

Mouth: divided into upper and lower lips, with a gap at the junction and squab at both ends. The volume of the oral cavity is influenced by the upper and lower jaws, and the total volume is semi-cylindrical. ?

Ear: supported by ear cartilage, it consists of outer helix, inner helix, tragus, opposite tragus, earlobe and ear hole.

Second, painting techniques:

1, judging from the large turnover.

Facial features and hair are important manifestations of the head, but these factors must be subordinated to and attached to the large volume of the head, and we must always pay attention to them, and the head modeling must pay special attention to several bone points that cause a decent turning point: parietal tubercle, frontal mound, eyebrow arch, cheekbone and mental tubercle.

2, the accurate grasp of dynamic and non-dynamic depends on the correct understanding of its changes.

Eyebrow arch, nose and cleft palate can be regarded as three horizontal lines, and the centers of eyebrow, human and mandibular tip can be regarded as the central axes perpendicular to these horizontal lines, which together constitute the dynamic line of the head. We can observe and grasp the dynamic characteristics through their changes in motion.

3. Ways and characteristics

Mode and characteristics are the spiritual content of incarnation. To make it correct and vivid, we must first rely on and understand the form, that is, "to write God in form, to be rich in form, and to have both form and spirit."

Sketch tool:

There are many kinds of sketching tools, such as stone pen, charcoal pen, iron pen, chalk, writing brush, pencil and pen. There are also paintings of diamonds and diamonds.

Different tools are related to the nature and composition of sketch, and tools will also affect the painter's mood and skills. The choice of tools depends on the artistic effect that the painter wants to achieve. Generally speaking, dry pen is suitable for making clear lines, and ink pen is suitable for expressing planes; Exquisite strokes can be brushed with a brush, and vast fields can be outlined with a pencil or chalk. Charcoal pen can be used for both.

From the size of the work, large-scale sketch works are suitable for drawing with charcoal pen, and the outline and carefulness can be carefully studied and analyzed for a long time. As for pencils, they are suitable for smaller sizes. There are few large pencils, while pen-and-ink drawings are even smaller, and they are often used for illustrations.

The monochrome performance of sketch makes the tool very random, and it can often be used comprehensively to create a variety of picture effects, so it is a very broad world.
