Cool dude - I dig the riffz, though I'm not a big fan of the Norma Jean-esque dissonant one, though at least rhythmically it's not too breakdown-esque.
I don't wanna be too critical of the rhythm playing, cuz I'm sure it's just scratch tracks, but it sounds a little loose in some spots, and I hear A LOT of those "wick wick" noises when you slide up and down the strings that drive me INSAAANNNNEEEEE - something to pay attention to when tracking the final versions, I'd suggest
(it's especially prominent in the riff with all the pinch harmonics)
And as for the solos, dude, my good god you can play - as you say, it's a rough canvas, so I assume the various off notes here and there will be remedied in the final version, but even with them the absurd speed and chops still come through, so mad props man. As always, I personally would suggest toning down the wankage and getting a bit more phrasing and melody in there, but there's some awesome ideas to be sure!
Mix wise, I feel the kick is a bit too clicky and the snare too low (though not in the blast beats). Guitar tone sounds good...for a 5150
As for the music, though, I feel the riffs kinda go all over the place and don't really flow together that well - kinda reminds me of Into Eternity, going from like chugging grooves to Yngwie-esque soloing to brutal blast beating, a little too spastic for my tastes.
