well, i see that you have really tried to make something decent, but it didn't came up how you wanted to. But i'm not going just rate 0 and not say anything, i'll try to help you a little by saying what you should focus on.
The first thing is: Stop scaling sprites. A lot of sprites in your movie has been made bigger or smaller, just don't do that, that's really bad looking.
Second thing: Start using 30 fps. In how many frames this movie has been made? 12? Your aniamtion won't become smooth and fluid if you will keep doing them on a framerate like that.
And the third thing: Add some sounds efects, start using vcam and maybe add some music. You can find a lot of tutorials at youtube how to do that.
I hope that this review will help you with your incoming animations. But remember - don't rush, wait with another movie to the moment when you will be good enough. Good luck :)
