This is a really cool animation! I was really impressed with the changes in perspective. One issue I have is that the audio seems to have a little bit of clipping going on. I don't know if you can hear the slight crackling like I do, but that's usually indicative of an issue with the quality or db's of the track.
It's really easy for me to overlook though because the music itself is cool and mysterious enough to add to the atmosphere of the animation. I really like it!
