hmm. well i like the colors overall, but what really destroys the pic is the hair... the semi-manga hair is just ruining it (it looks ok if it fits the picture, but manga hair in this picture.. no) also the mans hair/head in the bakground seems a bit off, like the hair is a bit too high up, seems like a helmet in a way.
also take a close look at his shoulder, its either HER hair HIS hair or a bag or something, it kind of fools your eye that it is his shoulder, which makes me dizzy :/
For the hair.. I really didn't do manga hair on purpose Which kinda sucks because you're the second one to talk to me about it. I don't understand the thing about the guy's shoulder, but I know it's not perfect
The pic was actually supposed to be cropped, so let me upload the cropped version at least....
