I often have trouble with shading. for example, when I'm drawing human noses, I have trouble with where to shade and what consistency.
Can you help me?
Answer From Kerry:
A good trick is to squint, to see where shading is needed. By squinting our eyes, we narrow down our vision which makes it easier to observe shade and shadows.
