Not bad.
I'm not a big Dragonball fan, but this wasn't too bad. Still, it was a bunch of random scenes. Yes, it's a trailer, but you have to understand that we only vote based on what we see. Anyway, the sound was fine and the music seemed like it was straight from the series so it sounded appropriate. I would clean up your illustrations a little bit, but I'm sure you'll get better as you go along. Decent overall.
