A VERY good animation with a great story. The story and animation are actually quite good. Sure the animation could use some work but the thing you may need to work on is the spelling and you may wanna fact check yourself.
For one thing the move Vegetto did was NOT the Big Bang Kamehameha. It was a simple kamehameha. The big bang Kamehameha was done like a ball and was performed by Super Sayain 4 Gogeta. You may want to correct this and future errors.
Otherwise the animation was great. Another thing you may want to do is make the on screen text stay for a little longer. It moves so fast that sometimes i had trouble actually reading it AND taking in the scene.
