Andrea364 hit the nail on the head, you have a single pad with a single high pitched arp that run the entire length of the song. Also it does desperately need percussion. The sounds at 2:30 were my favorite part, however you used them for your ending. Even so those same deep sounds at 2:30 could not have been used for everything either. whether high pitched or low pitched you need change and rhythm to keep me interested.

This isn't really danceable. Sounds like a bunch of creepy noise. The sounds around 2:30 are really interesting though. Could really use percussion. One instrument isn't all that entertaining!
