This only gets 3 stars for the story. As an animation as a whole it was very lacking. The narration was not standardised, but in virtue of that I can see where you tried to place emphasis.
But the story was great and you emulated the nature of the characters perfectly. I was ready to click it off but it was somehow, very, compelling.
This is a list of what you need-
Proficient Animators
Voice Acting
A secondary writer to help you with your work
If you go to the Flash Forum, and Collabs section I am sure you will find these things.
With the right people you may actually be able to create your own Dragon-Ball Saga.
Good Luck.
