Awesome!! Oh HELL yeah!!
I loved Mario RPG and I love this movie! And..AND! you used hand drawn animation! (Not that I dislike sprites, but HAND-DRAWN ANIMATION ROCKS!!)
The only thing that keeps it from being *absolutely* perfect in my book is the song is a little hard to understand. I understand that someone else did the song; so I doubt there's much you can do about that. I'd suggest captions; but then they'd have to scroll too fast. So I have no helpful suggestions there.
Otherwise, good job! Hope to see this in the Mario portal!
