You overemphasised certain moves and kept things very static. The biggest complaint I probably have is just on the smaller things. No loading screen/play button, sound effects were overpowering compared to the animation. Small things that I would have like to seen weren't in. (not story wise, animation wise).
Regardless, you did a good job. Obviously has an Alvin Earthworm style to it. If you need somebody to direct you and give tips/help I'm always available. I don't post my stuff here anymore on NG since it just gets flooded by the random hentai and crap.
Good job. :)
