Good work.
I was impressed with this. There are a few points missed that keep it from getting a high score, though.
For about the first minute or so, all the art is drawn.. Quite well, I might add. But then when they go into the nursery rhyme world, everything is a kind of pixelated photography.. Also, some voices would have been nice. I mean, a piece like this doesn't require voices at all, it stands well without them.. But adding voices to your cartoons is always a nice touch that I think people like.
