Very interesting.
Probably the second or third ambient track I've reviewed thus far, and gotta say, this one is pretty good too. It's highly dynamic, ethereal, creepy and eerie. It gives me a bit of the shivers listening back to it, which means you've certainly accomplished your goal.
While the instrumentation is mostly percussive, it is quite complex. That phasing/flanging deal you've got going on really fits with the theme, as does the bitcrushed kick. I will say that the hi-hats are a bit too harsh on the highs there. Could be a little more dulled with EQ or just a decrease in level, probably by about -6 to -12 dB, where it's still audible but not as "in your face." Same goes for some of that filtering.
Pads are pretty sweet; they're soft and unobtrusive. The bell-like leads you have fit well for some nuanced complements. They linger just enough to add to the ambiance.
If you've ever seen an anime called "Trigun," or listened to the OST of it, look out for two tracks: 'Blue Summers' and 'Perfect Night'. They encompass the kind of atmosphere and themes you were trying to achieve here (and maybe they'll help you in the future!) Very gritty and industrial like.
I like, I like. A good job, sir!
