Well...
I'm about as far from a metal fan as you can get, but you've certainly done a nice job, performance wise. I agree with the consensus, the drums are a bit upfront in the mix, and the bell ride is a bit pronounced within the kit balance. I caught 3 or 4 sharp transients, going into the bridge each time, that clipped off on you.
<some SERIOUS freakin' shredding in here dude, terrifically ominous, sinister sound you have!!>
I like the very strong 5ths theme you have going in the arrangement, suggested in the guitars and mirrored in the vocal harmony. Usually, parallel 5th movement is verboten in vocal arranging, because it sounds so sparse and relatively atonal, but when used for effect like you do, it's, well, bodacious.
Other than the drums being up front, the vox being a bit underneath, and there being a slight imbalance between the rhythm guitars (you could get away with panning them harder away from each other, it would declutter things and help the ear isolate each part), you've got a winner.
Well done!
