It's ok
It's not bad at all.
Some things that I saw gave me the "thats well done" thought. A good example of this is when Cell did a Kamehameha. Both the image and the sprite did the wave...very nice.
My advice for you is to clean up some of the sprites. Here and there I spotted some errors. And perhaps stop the music once the movie is over perhaps.
Nice effects you used in the animation though. May I ask where you got them?
