Good
You've got some interesting images/planes/cuts in your animation.
There are four things I suggest you to improve by now:
1.- You already know how to make motion tween, don't abuse of it anymore, experiment and begin using different symbols/draws/grops, you'll find your own animation style then. Don't abuse of the movie clip loops either, try to make it all more organic.
2.- Improve your backgrounds, give them more detail. There was an awful one when a "black enemy" jumped, watch animes and look how do they do it. Watching and learning from others can always be good.
3.- You've got four sound sources: music, dialoges, off voice, and sound effects, don't forget them in your first episode.
4.- Keep drawing and practicing. Anime, they say is the simplified version of manga, still, it needs a lot of work, practice and study.
Keep going.
