Nice tune
Its not so much the volumes are bad, its that the mastering doesn't put things appropriatly in the high end or low end.
i find that when i play guitar, i get my best sound with all low end and high end. I just cut the middle right out. When you shred you peirce the soul, when you palm, your the legions of hell. The dynamic works out well.
It sounds too flat, and thats one way to fix it. Otherwise this is totally awesome music from which to destroy your enemies to.
