Needs some work
In my opinion, your first release of something to the public, no matter what it is, shouldn't be a "tryout". If you want feedback from experienced users, you should publish it at the forums first, or you could just try to finish it up by yourself and then publish it as a completed proyect.
Appart from that, taking in count the simplicity of the animation, it's not very bad for being your first. The animation is smooth at first, but then it becomes abrupt when the girl turns. Althought you could better it, you should start a new proyect, like a movie or something, as I could supose that you had worked with other animation programs before and you know the basics of animation.
P.S. To be just an animation tryout the drawing is cool
I wish you luck and I hope that you succeed
