The first 2 beats of the main rhythm guitar sound like the start of a Blue Oyster Cult song. I would reccommend singing a little closer to the mic becuase I am hearing more of the sound of the room than I should be, unless you were specifically going for that sound.
Unless I am mistaken is the guitar track looped every bar?
Sounds cool though man. The bass is sitting pretty nice. I really like the acoustic interlude part... very nice.For the drums.. maybe eq the cymbals a bit and take some of the high end off, and color up that snare a bit. Rock on.
