I love the intro, I always feel like good driving rock has much more impact when it's preceded by a slightly off-beat rhythm or weird structure, and then when this does kick in it hits all the buttons. Your voice sounds really versatile in this song as well, it seems to shift between various tones which is cool. The spacey bit comes in at the perfect time to hold my attention but I would have liked a short burst of uber-rock outro or something instead of the fade-out, not to bring this down though. tight as hell, amazing effort.
