Hmm...
Seemed quite empty in the beginning (I'm sure you know what I'm talking about), but honestly this would make a nice 2-minute song if you wanted to get rid of the constant waiting in the beginning. Don't get me wrong, I understand what you were going for... but you actually need something to keep the listener enticed while the music / intro is building up.
After all was said and done, it was a pretty nice track and I can tell you put some work into it. You got a 4 outta me.
