For me, I don't mind seeing some post-editing manipulation, but this seems overly processed. The magenta is blown way out there, but then again, that could be the effect you were going for. I do wonder what the original was like before manipulation.
Not crazy about the oversaturation of color, but I see the point, given the challenge. I think if the background were more of a contrasting color, it'd have more of that Andy Warhol feel to it.
oo very pretty. it seems a little over contrasted, but i still like the colors. there's a little blue line thing at the top left hand corner, it kind of annoys me, but awesome job! good luck
