1. Observe the object and arrange the composition. Taking the image of the elderly as an example, the basic characteristics of painting the image of the elderly are: prominent facial bones, emaciation and muscle contraction. Take the reticle as the central axis, determine the proportion and distance of the five senses, outline the big shape, and use the pen in place and accurately.
2. On the basis of drawing, establish a three-dimensional relationship, reflect the body structure of perspective modeling, and master the basic movements of head, neck and shoulders, as well as the distance between nose, eyes and glasses. Then change from a large straight line to a small structural line for adjustment and deepening.
3. Continue to depict the structure and light and dark sides of the face, so as to achieve light and dark contrast and even tone. According to the structural line of the face, the light and dark tones and the gray face are brought out in turn, so as to achieve a seamless integration, without isolating a certain part or breaking the coordination of the whole picture.
4. Add a smaller gray surface to enrich the picture. Analyze and understand the relationships and changes of the whole avatar and the influence of light on the avatar. Pay attention to the performance of the old man's forehead, not too real, otherwise it will lose its texture.

FREQUENTLY ASKED QUESTIONS
1, body painted "crooked"
This is an error caused by poor drawing. The object in sketch is characterized by "quietness". Every object has its own position and center of gravity, the center of gravity of symmetrical objects. At its central vertical line position, if the vertical line is not vertical, the center of gravity of the object will be unstable, resulting in a "crooked" error. There is another reason for the mistake of drawing "crooked": symmetrical objects are drawn asymmetrically. The solution is: when drafting, both sides should draft at the same time, and don't wait until one side is finished and the other side begins.
2. The picture is too "empty" or "full"
This is an error caused by improper composition. If the object is too small and too concentrated, it will cause the picture to be "empty"; If the object is too big and scattered, the picture will be "full", and even sometimes the picture will "not fit" the object. The solution is to find out the combination form of the whole object at the beginning, make positioning auxiliary lines according to the requirements of composition, and don't change the positioning lines of composition easily in the future, otherwise it will destroy the original intention of composition.
3. The contour line passes through the "virtual"
This is because the painter mistakenly thinks that the more three-dimensional an object is, the more empty its outline is; The more objects behind it, the more virtual its shape is. The solution is to understand the phenomenon of "binocular parallax" in vision, learn the transformation relationship between "line and surface" in modeling, and express objects objectively without the influence of "subjectivity".
