Katara Moonscape

When I was finished with this, I was actually pretty happy with it, but as I got to looking at it I started seeing all the flaws. THEN I just had to go and spill cherry coke all over the bottom, so I had to crop off a lot of the bottom portion. You could actually see her shoes before and a bit of the ground. And THEN my scanner had to go all poopy on me so the color is all funky. Please, if there is any advise you could give me to make it look better, don't hesitate to give it! (At least about the coloring. I don't know if I can do anything about the shapes...)
