The first thing I notice is how constant the speed is.
You need more frames in certain places, like when it starts and ends it should speed up/slow down..
I guess the areas where she is fighting against gravity would be slower, but maybe not slow enough to warrant an extra frame at this framerate?
Unless you're looking for a super ninja move that looks more unnatural, but even then I'd want a slowdown towards the end because she stops were suddenly.
And I think there could be more forward momentum, there might be too much spinning in an area that is too small.
