Right off the bat, I want a sub below those growls, right center, probably a square wave for presence.
Otherwise, loving the chaotic noise going on here, and how the snare blends with the reesy rhythmic drones in the intro.
By the time the 2nd snare enters, the high frequencies are a bit overwhelming. The ring on that snare is right in the frequencies of my tinnitus and could probably be rolled off slightly without losing any edge to the track as a whole.
What I do love is your play with distortion and saturation throughout. Beautiful. However, I do feel there could be more contrast in arrangement, like say dnb drops with more fancy noises, as opposed to the slower dubstep like dirge we have for the second drop. To explain what I mean, "verse" sections with percussion arranged as you have for your second drop, and drops as dnb. Perhaps implement more obvious builds as well.
Mix feels like at points it is too wide, very high mid and treble heavy, with not enough low mid and sub to feel pushed. Could potentially be suffering from over reverberation and a very loud mix prior to compression -- that will lead to this issue very quickly, sucking energy from your bass as low mid and sub frequencies on your wet reverb push your bass out of the way.
Due to over reverb and delay, as well as some eq choices, I am having a hard time hearing your cymbals and hybrid cymbal percussion. Panning play, transient shaping, and simply moving things out of the way to make room for the cymbals will help that.
I still really enjoyed it though. Great work, and love the cover art.
