Rainbow Girl Dance

I was in the mood to color up some rainbows, wanted to try all of the different layers, and make someone who is moving. This monstrosity is the result.

Tried to make a background with actual trees and stuff. It was fail though... Reminds me that I need to practice more on backgrounds.

Don't think I got the way her body flows goes with the way she is moving. It was the closest I could get to it. But if anyone could point out where I went wrong, that would be great.
