Liking that sub.. the subtle wobble is great, and all the other mid bass sounds and effects you got goin on are pretty sick too. The overall atmosphere is deep and dark
Kick seems to be lacking something, maybe a bit more low end is required. Snare is tight tho
My other complaint would be variation in the beat.. it sounds too static at the moment, with the same or similarish hi-hat sequence going throughout, I think it needs more percussion to give it some more shuffle. Another trick would be parallel compression, I cant quite tell if you've tried it because it is a subtle effect, but it could bring those hi hats alive.
This reminds me of 80s sifi movies. It has a really cool bad ass feeling to it that could suit creatures from outer space. I can't really comment on the mix because I don't have good speakers. But I am diggin' the darkness of the song.
