That bit at the end was pretty funny, I like this for a school project, so I'll try and grade it like a teacher.
Animation itself isn't spectacular, but it isn't trying to be, so that's fine. I think the focus of doing this was probably to have fun and practice your animation.
I liked the sound effects that were added in, although they did get reused a little too much. The one where the soccer ball hits him in the face made me crack up, though, it fit perfectly.
A-, the animation itself isn't wonderful, but I thought the humor made up for it decently well.
