Ladies and gentledudes,
I've been sculpting this hand as another anatomy practice project. The point here was to accurately capture the skin folds in this specific position. I've been mostly using my hand as reference and then went a little overboard on wrinkles. I'm sure the result differs on different people. I also wanted to create a skin shader that does not rely too much on SSS (Do you guys say triple S or S S S? I'm curious).
Sculpted and textured in ZBrush. Groomed, shaded and rendered in Blender and Cycles.
