Great graphics, bad... movie
First off, that show is retarded. Anyone that disagrees is retarded.
With that said, you need to choose to do something else with your talent with graphics. Graphically, you did amazing. But the whole retard show ruined it. If you're going to make a fan animation based on an anime, choose something more respectable like FMA or Evangelion, but only if you have no imagination. Otherwise, come up with your own creation. Make your own characters, your own story, your own world. Be productive, as making a tribute to a bad show isn't very progressive. Sure, it'll help you improve your artistic skills, but it certainly won't improve your imagination, which you will need later on to complement your art. All in all, just avoid DBZ.
