3d Animation

This is a 3D animation I made last year. It was done completely in MAYA.
We had to do an animation based on a nursery rhyme.
Thought I'd post it here and see if anyone wanted to comment as I always like to get feedback so that I can improve. (Constructive criticism is always welcomed)
Its not perfect I know, and the sound was only added later as I'm not very good at sound.

What song is it?

and nice job =)
Its called wake. its the litttle instrumental bit off the start of Minutes to Midnight
