Fallen Angel?

This was supposed to be a bad sketch of my character Arael as a fallen angel. Apparently not. I just wanted to experiment with colors and coloring. I know the lines are really bad, that's why I said that this wasn't supposed to be serious. And please don't even start on the backgroud. I hate it.
By the way, do not ever make wings sketchy lines and start coloring it. I've learned I can't color sketchy lines.

Critiques on coloring if possible.
