The movie is amazing, but I have 3 little things to talk about:
1. You could add the "sonic boom" effects to some punches (but not the every punch, cuz that would be quite annoying).
2. There should be much more air fighting and I know this could be hard to do, but you could make 2 photos: first being just the background, and the second being the figures standing on some objects and then just "photoshop" the objects that the figures are standing on, so that would look like they stand on thin air).
3. At the end, where vegeta and goku are knocked back, the shouldn't sit, but "crouch".
If you don't understand something, please send me a message and I'll explain it.
That's all I have to say about it. The rest is really well done and It deserves attention.
I hope you will get some fame from it.
