This is pretty goddamn good, my dude. Next time you're putting together a drop, try playing with having an 808 or triangle-wavey synth play a single deep note and manually automate a detune on the fucker. If it needs some fattening up to get that really crunchy deep drop, throw on some mid-freq distortion pre-pitch shift/detuner.
And maybe some speedy hi-hat things? That might just be me though, I love a good rhythmic background hat piece behind that beat.
Otherwise this all sounds real good. Reeeeeal gooooood.
