maybe not the best you could have done
i'm sorry, this just isn't very good. i mean i'm sure you know this already, but it still needs to be said. i can see how you've got the beginning of something decent going here, and this isn't an awful movie for a learner, but i did not enjoy watching it very much. try using shape tweens between keyframes, they will work wonders for choppy movements and weird size changes as happen when you animate frame-to-frame. shape tweens are usually a bitch though, so maybe use different layers for different body parts. hard stuff, yes, but this is the road of a great animator that you have chosen to travel down.
