First of all, your painting skills are an important issue. You have a certain level of structure, light and shade, and overall perception. Only when you have a foundation can you establish your own style. By the way , there is still a big difference in Chinese sketch styles between the north and the south. The ones in the south are relatively delicate and graceful, while those in the north are relatively vigorous.

As for color, emphasize the boundary between light and dark, find the main boundary between light and dark and the secondary ones, emphasize the important ones and weaken the secondary ones. Do not make the picture too gray. There must be a main light source, even if When painting, it is difficult to distinguish the light, so you should try to find a tone that can complete the painting.

As long as the structure of the eyes is accurate and the light and shade are reasonable, there won’t be much of a problem.

Blurred distant views should be drawn together with the junctions of objects. Hair, etc. should also be considered as a whole. You cannot draw too dark at once. Draw hair according to the degree of completion of your painting. If you draw too dark at once, the hair will look like it is flying out.

I can only say so much, in the end you still have to rely on yourself!
