Hey there! Ideally, you should establish the direction of the light so you can paint the shadows more effectively. Otherwise, if the lighting isn't clearly defined, there will be light everywhere, and the illustration will end up looking a bit flat. For example, both sides of the face are illuminated, when ideally, the right side should remain more illuminated while the left side stays in shadow. Separating light and shadow helps give things better volume. The same applies to the hair. Keep in mind which areas of the hair are exposed to the light and which areas will be in shadow. Separating light and shadow makes it look more believable. Also, think about the ribbon-like locks of hair as you paint to give it a better shape. :) Hope this helps! | Artwod Feedback
