Interesting, for sure
Firstly, about the sound: I watched the deviantart version, yet I still didn't like a good deal of it. That's only my fault, though - the quality of the sound was good, but I just didn't like very much the music that was played. However, as the animation progressed, I got more used to it, and it even seemed to fit more.
My favorite animations there were probably the second and fourth. The second - with the room - impressed me immensely, and the in the fourth - with the fight - I think that if not the characters perfectly, then the motion itself was rendered superbly.
Overall, this was certainly an original and creative piece.
