The character's avatar is the most important part of the character and is where the character's spiritual outlook lies. The character's avatar consists of the face, facial features, neck, etc., and the face has different shapes. Some people divide it into "Tian, ??You, Guo, Yong, Mu, Jia, Feng, Shen" and other fonts. These shapes It is mainly determined by the bones of the character's head. Therefore, when drawing a head portrait, you must first draw the 10 main bone points of the head: roof ridge, forehead mound, parietal bulge, brow arch, nasal bone, zygomatic bone, temporal bone mastoid, chin Angles, mental protuberance, external occipital tubercle; and 8 bones of the head: frontal bone, zygomatic bone, nasal bone, temporal bone, parietal bone, maxillary bone, mandibular bone, and occipital bone.

In addition, it is necessary to understand the head muscles used to depict character expressions, and to analyze and study the physical structure of the head, that is, the direction of movement of the head, the light and dark relationship caused by rotation changes, and perspective. Changes, such as looking up, looking down, squinting, looking straight, looking sideways, etc. Understanding and mastering these skull structures, head muscles, and movement postures play a vital role in drawing a good avatar. It is like building a house. After the frames and beams are erected, the basic structure is in place, and then "decoration" is carried out. "It's not difficult.

Facial features are the main characteristics of a character. For example, eyes are the most sensitive organ that conveys inner emotions and perceives external things. The so-called "insight into everything" means that human eyes are very subtle and have the characteristic of penetrating into the subtleties. Therefore, it is very important to depict people's eyes. The eyes are generally composed of these parts: upper eyelids, lower eyelids, eye slits, whites of the eyes, pupils, and iris. The eye shapes can be divided into square eyes, round eyes (tiger eyes, almond eyes), red and phoenix eyes, triangular eyes, etc. Due to the infinite changes and activities of the eyes, it performs scenes of "vivid drama" on the characters' faces. For example, the eyes of the elderly are mostly experienced and weather-beaten, showing the perseverance, stability, and wisdom unique to the elderly, and are full of kindness and kindness; while the eyes of the young are mostly in their prime, energetic, and expressive. Showing the unique vitality of young people, they are lively, cheerful, enthusiastic and frank; some are unrestrained and handsome, some are quiet and graceful, some are bold and enthusiastic, etc. Analyzing and studying the eyes of these different characters, different ages, and different styles is very critical and important to grasp the entire object, and it can even be said to be a success or failure. Beginners can also refer to how other excellent works depict the eyes of characters, such as the classic works of painting masters such as Leonardo da Vinci and Repin, which will be helpful to them.

You also need to be familiar with them. Eyebrows, to a large extent, can match the eyes, convey emotions and express a person's temperament and personality. The shapes of eyebrows include sword eyebrows, willow leaf eyebrows, splayed eyebrows, lying silkworm eyebrows, moth eyebrows, longevity eyebrows, etc. Some of them have different expressions. Heroic, gentle, and some show fierceness, cunning, etc.

The expression of the nose on the face is also very important, and it plays a decisive role in characterizing the character. The nose is divided into nasal bones, nose bulbs, and nose wings. The nose can also express the character's temperament and personality. A wide nose shows the character's honesty; a narrow nose gives people a sense of shrewdness and selfishness. The nose is in the middle of the face, so pay attention to it. The expression of length, volume, and shape features on the face is another key point in characterizing the expression of the character. The center is above the eyes, followed by the upper lip, upper lip tubercle, corners of the mouth, and lateral labial grooves. The lower lip and chin-labial groove, as an organ that expresses a character's expression, always have an isolated shape. Each person's expression is different, some are beautiful, warm and generous; some are petite. Beauty, elegance and beauty; some people regard thin lips as the beauty, which makes them appear eloquent and articulate. Therefore, depicting the mouth and its surrounding parts is a major difficulty in sketching. Beginners should carefully understand and observe its features when drawing the mouth. The shape, structure, direction, the lip lines of the upper and lower lips, the curve of the lip gap between the lips, the corners of the mouth, the philtrum and the chin-labial groove are very subtle, but with a little expression, they look amazing and have endless charm. .
