Heheheh...
This is excellent. Maybe it's for lack of trying, but I haven't seen much of Rayman here on Newgrounds. Even better is the fact that it's based on the often-ignored first game (freakin' Rabbids >:().
Anyway.
The animation is good, but that's not the real reason the movie stood out; the real reason it was the style of humor (my personal favorite was the third short - having traversed Picture City many times, I can relate).
Why didn't I give this movie a perfect score? Well, because it's too short. I'd like to see more shorts in the same style; in fact, I could easily see a Rayman collab in the same vein as the highly-praised Sonic Shorts. Great idea.
In any case, excellent work.
