Really cool piece! I can't really see anything wrong with the anatomy either. The only thing I could think of was that maybe his fingers/hand should be visible on his left arm, but that might have been on purpose, it depends on how he's holding his hand.
I may actually be how he's leaning, but I don't really see anything wrong with him right now. Very awesome! I love your colors and the textures you apply to all your paintings. I think what I enjoy the most are the character's outfits. I love them!
OOH I tried everything-- flipped it horizontal, vertical, zoomed and unzoomed for a hundred of times ad still have no idea what's wrong aargh! Anyway, glad to see you again! And thanks, though the outfits always were the hardest part for me.
