Not bad really

Your right it is not the greatest, but considering the fact you made this in one week in school, and its your first time doing this its a pretty amazing animation!!! Just remember time and practice make perfect. Keep it up.

Very good

It is very well done for your first movie, next time though, make your text a little bigger and get to the point of him breaking the ride a little faster. I hope you are inspired to make more videos, because the more you make the better youll get.
