I know I'm a bit late, but I still tried my hand on this challenge. Learned so much from this by observing Loish's work. The complexity and skill from bounce light to the different hues in shading just made me appreciate Loish's awesomeness... And hurt my head as well, 😅 but I got so much from this. It was fun.
I think a big flaw in my work is I rely too much on soft brushes to clean up my piece. I should be more accepting to the randomness of brush textures... And I gotta keep studying anatomy. 🙂
