Thanks for the feedback! I think I'll have to bring a mau5track to reference with in this project.
- I'd go even further with cutoff automation on that stab. + wet it in reverb a bit.
OK, I'll try that. My problem has been that the stab sounds kind of dull and boxy with the cutoff set low, and I'm not sure how to fix that. Maybe a reference track will help.
- I think it needs some atmospheres or drones. ...in mau5e's manner may be. 
I have been thinking about this, but thus far I've been too lazy to find samples/learn how to use those. Will help to make the intro more interesting for sure.
- Drops might benefit from a bit more percussion.
What kind of percussion did you have in mind? I kind of felt that the basses and synths were enough for percussive elements especially in the first drop, so I never even considered anything but the basic drums.
- That beak down neeeeeds some heavily reverbed pads. 
Roger. I'm also now thinking to make the kick "booms" bigger. The only problem is that I'm running out of memory with this project (last one I'll do with a 32 bit daw), so need to start bouncing some stuff if I'm going to add any instruments.
