there's two things that could be improved imo
after the intro, the drums disappear and you've got all those electronic noises. when it comes to the second bar, they're all repeated. I think it would be better to have none or fewer of them after the first lot, to bring in tension and suspense. if you could get some pads in the background to make the atmosphere more ominous that would be good too. the vocal sample just before the drop isn't very clear (i can't make out what is said) so maybe push that to the top of the mix?
also, there's this one voice that appears which just doesn't fit that nicely imo

i dunno if you've ever heard lowdown by xample?
well, you've got some great phrases which 'answer back' previous phrases... but that little sound, and to a smaller extent the one just before it, could be replaced with something of that kind of timbre and mood. this note, that i sampled, imo should be lower than the one before it.
even with these things you've got a brilliant track going on there; i just want to help you make it perfect.
those deep grimey sounds you've got are sweet and used with great care. i hope there's a bit of sub-bass in there so you can play it nice and loud?
imo you could make great neuro or dark dnb too. or dancefloor, it's all good.
