The music was decent. Every FBF needs sound, and this was a cool song. The animations were a little neat, since they were mostly mirrored, which is unique.
This wasn't really that interesting for an FBF. The different things you did seemed to be relatively the same throughout, which just made this pretty boring. You may want to think about increasing the framerate at perhaps try to sync this a little more to the music to make it more interesting.
