It's a little weird how when you see masters working on anatomy they create perfectly ordinary people, it's like as students we begin with the muscular/sexy folk, and when we master those factors we begin to hide the amazing stuff amidst the boring stuff. The character designs for The Last of Us and Grand Theft Auto are good examples of that. Though Last of Us is a still pretty idealized with its walk-on characters.
Anyway, your dude with the pecs and the tree-trunk arms made me think of that.

Study some more flesh tones. Your characters would benefit from a little warmth and extraneous colour, though they look pretty good now.
