Hey slumbermachine,
Nice track, I like the auto-panning on the hi-hats, but they're too forward for my ears (sorry, I have sensitive ears). I like how you're building tension with some of those wavering sounds that sit on one note throughout, and the music that's going under those filters is awesome as well.
60 hours mastering this... that is crazy. At least it's done now. Good job on this.
