It was cute, but I think that (and this is my opinion, you don't have to agree) chibi's shouldn't have tits and ass flaunting. It's quite disturbing to see an adorable little chibi, looking maybe five years old, with boobs, and the back shots were quite disturbing.
Overall, it was a good idea, and the animation was great, but I just couldn't seem to get myself past the boobs.
It's probably just me that thinks that though.
