Aww, thanks! I called it messy because of the following reasons: 1) The animation is slightly choppy, but that's because I'm working on my tweening. 2) The colors are kind of off, but I didn't pay much mind to them. 3) The colors come out the the lines, giving off a messy and or lazy aura.

Tweening is when you slightly move something each frame. For example, each layer of this girl is being moved slightly every frame. It's best to tween with the new editor, though.
