Truly the fastest Amen break I've ever heard.
In all seriousness, I really think you need to work on the mastering here. It's mildly painful to listen to, in the sense that it makes my ears feel uncomfortable (Not in the "I think it's really shit" way). When every instrument is that loud, then it all kinda mushes together and becomes muddy. I'd pan your instruments more, bring down the volume on them as well, and try to make sure there's a range in the loudness of each instrument.
In terms of atmosphere, it's pretty scary. I actually quite like some of the instruments that you've used, and the samples fit very well. Definitely a strong point. It's a shame that it's a bit repetitive. A bit more variation in structure, chords, etc, would have helped a lot.
Keep at it!
