This is pretty sick actually. My biggest concern is how stereo the sub frequencies are. everything past ~140hz and under should NOT be stereo. Audiotool doesn't have mid-side eq, so you'll have to turn each channel mono individually, as opposed to just slapping an eq on the master that does it for you.
i'd also like to hear different forms of percussion. i feel you could get very creative with percussion in a track like this.
good work so far, nice to see that you're improving!!!
