I think it would make more sense if the bird poo was running over the other side of the chin (from us), since the birds ass is over that side. Because now it makes me think that the bird has either switched sides from sitting with it's back to us, or there's just something wrong.
I really like the idea of this though, and everything looks so smooth and nice. Lovely colours! Nice to see some AA-free work from you
I especially like the clenched fist though, probably because it's so detailed. Wouldn't have hurt to try and add the same amount of detail to his clothes. They seem a bit flat compared to how everything else is shaded.
Super cool piece, ptoing!
