Ehh....
I'm sorry, I have to write a review here. While the technical aspects are all pretty good, the actual content leaves a lot to be desired. I applaud your animation and drawing skills. The animation is pretty smooth and I especially appreciate the good lip-synching. However, any of the fire/attack effects are pretty below standard, and look pretty half-assed compared to the detailed characters. Also, the "floating" transparant bangs that almost every character has is awfully distracting and just doesn't mesh well with the rest of the animation.
Now, I'm trying my best to be nice here but I just can't, I'm sorry. Your story-telling skills are pretty below par, even for DBZ standards. You've failed to A: Create a half-way engaging or surprising storyline, B: Make me give a shit about ANY of the characters in the smallest amount, and C: Create dynamic and interesting battle structures that DBZ is famous for. You've also failed to create ANY sort of dramatic tension, and I could pretty much tell how this entire story would play out from start to finish. Except, I admit, I thought you'd have the Jamal spared and become an anti-hero. All of the characters designs are pretty samey. In fact, I think Deeth and Chris are the only ones NOT wearing a wife beater, and they're ALL wearing cargo pants or something. Also, some of the sound effects are startling and unwelcome (Chris climbing a cliff....)
Come on man! You've got serious animating talent! How'd the hold-up in the writing department even start if you had a year and a half to work everything out!? Surely you could've devoted some time to creating better-looking fireballs or finding some public domain sound effects that sound better?
PS: I have to give my shout out for Deeth. Deeth was the best character in this series by far and actually, one of the more interesting to listen to. I don't know if you intended that or not, but still. Deeth is what really pulled this movie together.
