D00d, some crazy stuff's going on! Keep it up!
While the drop that starts to buildup around 1:10 is unique, and a change in style, I feel as though it doesn't transition very smoothly. It feels like you only used two different melodies in this, without enough noticeable variations in them to make it feel that interesting. That's the smoothest ending to a song I've heard in awhile, though. Nice.
