Pretty good actually.
I won't lie, given the review before my own I wasn't expecting much. I have to say, however, that this was pretty good fun and I thought your choreography was original and fluid.
The only things I can nitpick on are that I personally don't like that particular Goku sprite (although I can understand why you picked and it doesn't affect my score), the Sonic/DBZ crossover has been done to death.
All in all it was a good flash and I hope to see you grow as an animator and see your future work.
