well
it was bad. but here's what you can do to improve:
the absolute most important thing for you IMO is add sound. sound effects and music are really important for a good movie
the next thing is work on the artwork. i know drawing on flash isnt the easiest thing but you can do better than that.
finally to improve the animation quality you should add more frames so the animation runs more smoothly. some bits are laggy and it doesnt look very good.
I hope you take these things to heart for i believe someday i could see you on this site as one of the best out there
or you can be like me and after one not so good submission quit and never animate again haha
