hmm...
I see many things like this: good drawing and the right ideas for animation, but the actual animation is choppy and confusing, possibly rushed. try to make your animation smoother by adding more frames to movement. make sure there are slight pauses at appropriate times so the viewer can realise what is going on. watch your movie and observe places where movement is unclear, then go back on work on that part. look at how you and other people move to get realistic movement. animation like this takes time and commitment which it didn't look like you used in this. If you really want to be good at animating, and produce something people will enjoy and admire, you have to keep practicing and spend time on what you do.
