Great song. really great smooth sounding intro and some really catchy riffs in there. probably the only thing i would have say in relation to negatives is that you had some really abrupt changes throughout the song, and personally i think it would be better if you had built into those changes instead of diving headfirst into it.
I love it.
good to know.
