What a lovely image. This has a great animated quality and I love the color palette.
Here's a couple of suggestions. I love the "dragged" quality you have with both heels still on the ground. But with how active the wind is, I wondered if maybe changing her leg position would help add some energy. So I gave it a whirl here to see if it worked. Feel free to adjust as needed of course.
I think you could simplify some areas too. I darkened the trees a bit and lost some of the highlighting around the image. The wind marks you have by using a single weight line seem like they need some help. I added two marks that show more of a "thick to thin" type mark which can add some design element there. I'd change all of them to have some sort of weight variation.
Really cool image! : )
