Awesome.
The only thing I don't like is the clean guitar sound post-intro. I'm not sure what it is about it that I don't like. Definitely something tonal, though.
If you have Guitar Rig 3, I found an acoustic guitar simulation preset that kicks ass. Just let me know if you want me to send it your way.
Your vocals in this are phenomenal. I'm very, very impressed. Great vibrato, notes are spot-on. The delay was a little long in my opinion, but that's just me.
Overall, an awesome song that is absolutely worthy of however much time you worked on it.
Metal! \m/
