Very nice
The animation was very nice and truly interesting. I also found that although the music was off at the beginning, it seemed to fit a bit better when it approached the end. The main problem with the music sync was that the music started a second too late, which threw off everything else.
The other large problem was the keyboard animation sync, in which the faceless character hit the notes at very odd time in correspondence with the music. Nice work, can't wait for more.
