Not Bad.
That was a giggle, I think your animation could use bit of help. Next time you watch DBZ (I can tell you've at least seen it.) and try to mimic the tricks they use such as showing movement without actually moving the character. The music as a very good choice, fast paced and light humor matched your animation really well. Great use of sound FX! The character were nice in concept however it think they could use a bit more contrast to we the viewer can see all the detail you've put it.
Good Luck on your next Flash!
