1) build a new layer, name it "skin color", then use the front view (skin color) to use the sprayed tool to outline the complexion.

2) in this layer, when skin color is in place, some places can not be coloured and consciously keep some flying white.

In this way, we can not only express the relationship between light and dark, but also make the picture move deeper.

3) when painting the relationship between the eyes and the dark, proper smearing tools can be used to make the eyes have a sense of hierarchy.

The color of lip and eye shadow can be considered in accordance with the color of clothing.

4) the color of hair can be used more widely, such as dark red, dark blue, ripe brown, brown and so on.

Do not use pure black or spray tools.

Attention should be paid to the relationship between the sphere of the head and the bulky feeling of the hair.

5) in the process of human coloring, different parts can be placed in different layers for coloring. For example, before the hair is coloured, a new layer will be created, then the hair will be colored.

This will help to modify the screen.
