Cool structure!
I really like the journey this track takes you on. Definitely reminds me of sci-fi!
Sfapil 2 has it down I think. I suspect you've used an FM synth on the bass... And if not, then a few of your oscillators are downtuned or something. It would sound brilliant if it sweetened up in some sections and then you had your weird harmonic thing going on later as an effect. It just sounds a little discomforting all the way through and does disturb the beautifulness going on elsewhere.
Excellent effort! /fav!
