that might be true if the costume was like any of the other robins since it's not we have to look else where and the only thing that separates this robin from the rest is the way his hair is (yes I know tim had his hair like that as well one time but he was older)
Awesome work. If not it isn't too much trouble, could you say which Robin is this? He reminds me of Dick Grayson, but he could be as easily Jason Todd. Robin is one of my favourite heros of all times, great job, really.
