I agree with Frost. The background looks completely different from the rest of the piece
It looks like you used some kind of perspective tool for the background and didn't bother to clean it up.
oh dear god I think im blind if i missed that. Lol Anyway it reminds me of the way No more heroes 1 displayed the assassin's name. I can hear it now " Shooooooe"
His username ;D
I like the background perspective, but it's a bit odd to have anti-aliasing in some places but not others
Nice poses.
