Let me start by saying...
You have alot of good melodies throughout the song, actually, they are awesome. But the problem is that you're not detailing them enough, and you seem to just through them all together. You gotta let it flow from melody to melody, even layer a few o add highlighted sections. You should just improve on it a bit while its still in development.
Really, just add a descent bass and improve the drums a bit, plus, you gotta use better transitions as well... let me know when you upload another update and i can review it again for you^^
