Not bad, but...
The idea is really basic and nothing's really going on. The animations weren't smooth at all, in fact, some of them (not all, just some) were bad. The were pretty boring, there could've been some more creativity in textures or different colors (colored cardboard paper?). What I'm trying to get at is: it's boring. Don't get me wrong, you all have talent, but you definitely could've added some more work to it.
