I like the beginning of it. Alot, actually. But when it just dies in the middle of the song, I'm left wanting and anticipating a bit more when it's about to start up again. It's a pretty ill beat in the beginning, but I'm curious as to why you just have it die in the middle of the song for no reason for a couple of seconds. It really does no justice to the song.
Work on a filler for that part DEFINETLY, in my opinion. Once you've got that, then maybe it'll be easier for you to figure out what that missing component you think isn't there is.
Otherwise, keep trying, man. You'll get there! :D
