Now that the overlay issue is fixed it looks great . there's a bit of a blip on her right arm (our left) though, when it reaches its left-most point. It goes really fast, but my guess is that the highlight goes away and is replaced by the shade color. It makes that one frame slightly odd.
Besides the overlay issue, her right arm should have one of her long white gloves. The two shade palette gives it a cutesy feel. Good job.
The animation needs to be set to replace frames, not overlay frames.
I love your style and animation, and there's a great deal of both here.
