Sweet.
The drawings were great, but it shows that you're used to animating with sprites. A good improvement compared to Sonic vs. Knuckles. The lack of sound in some places wasn't too good for the presentation, but the sound fx othewise made it kick butt. The drawings impress me a lot actually, I really like them.
As a lot of reviewers said, it is Dragonball Z-ish, but I really don't mind. Someone who doesn't have a lot of drawing experience will probably not like this, the actual presentation of your work isn't as good as it could be, thus the details become more ignored. Otherwise, pretty good. ^^
I've never heard of NAZO, or whoever he is. You're seriously going to remake this? It's gonna rock if the original is this good already. Good luck!
