Re: dines sketch book
One thing you should consider, especially with skin, is that the translucent layer of it spreads the light more evenly beneath the surface. That also goes for ambient or bounce light, which would result in far less harsh shadows, where ever light still spills over. Darker shadows would only be in real creases or spots where truly hardly any light can get to. The result is a more softer shading. Also to consider is the greasy specularity in certain places, which then would reflect light a bit more. Things to ponder and study. YOu'll totally get it! Just try to study carefully what you're looking at and always consider what ambient light your background suggests!
