i think the beat is aight, the second melody that comes in sounds a little strange, almost like it doesnt fit with the original sound you have for the first melody. the little string hits are cool though, it brings it all back together. i think you compressed the master too much, the bass is really overpowering and when its absent everything else gets a lot louder. you should add a kick as well layered on top of the 808, that would add some more feeling to it.
