I'll be honest. The animation was extremely AWESOME, I'd give 5 to the animation. It makes me want that this was a game instead of an animation.
The music was cool, but nothing different than most of the cool musics out there, I mean, this is probably something more "personal" but, the music didn't make me feel like "I HAVE to hear this again", it's more like "I can hear it on a radio but not on my ipod". For the music I'd give 3 stars.
So, that make a 4 stars review.

A very beautiful animation, nice work.
I'm not sure, but this video was on nintendo video (nintendo 3DS)? I think the first time I saw it was there...
