Sweet mother of bassline, you've definitely did an excellent job on creating this 'dark', 'eerie', 'morbid' kind of vibe. I'm really digging that.
Nice use of individual sounds mixed together. Sounds like a lot is going on, yet it fits.
I would definitely layer, re-EQ and boooost that snare like a moffuka' though. Personally i would take out some of the body and put in a little more high end, a little more crackle.
Still, I'm really liking this tune.
