I've just written a comment but the silly server didn't save it...
The characters are well drawn and the idea is nice, too but the whole picture lacks some contrast. It is all white and there are no big details in the clothing so it might look a bit empty. I hope you can understand what I am trying to say. SO you need someone to colour it for you? Well, I won't promise anything because I don't know if I manage to do it but myabe I will try to colour it ^^
