Very nice dramatic shading. He's not about to be hit by a semi with its brights on, is he?
I don't really see anything wrong with the feetsies. He's not wearing boots, and lizard feet are pretty damn flexible.
Eh, I just started shading other parts of him, and I thought "What would a kuvvy look like with cheek bones and stuff?". Then it came about. And yes, I have a love for clunky bulbous feet. Can't seem to get it outa my system.
