Love the description.
Intro sounds very desperate. Enjoy the chords chosen
I think you could separate the attacks of the intro piano notes such that they sounded as if they were being struck by a person.
Bit crush in the intro is quite interesting. The guitar samples remind me of N64 Top Gear Rally. Actually, the whole track. If you've never heard of it, I recommend taking a listen; it sounds like you would enjoy it.
What would make these guitar samples stand out is if you had a double track on them -- meaning one instance 100% left, one instance 100% right -- but you would need a separate sample that was slightly different. I do actually like the machine-gun attack on them. It suits this arrangement.
What this could use more of is a punctuated bassline to suit those chuggachugs.
Also, your verse section around 2:56 is about the same as the earlier one. You can do more -- even if you don't change the melody. Just strip down the section to bare bones and add a transitioning swoosh, even!
Loop is not entirely perfect -- I recommend copying the tail end of your final notes as they ring out and pasting them to the beginning of your track for continuity!
Also, the bitcrush transitions into your drops are a bit clumsy. I recommend not reducing sample rate at the end of them but instead hi or lo passing out of them while reducing the volume. They are heavy in the mids.
Now, writing wise, this is very driving and I much enjoyed it. I'll certainly be following you and favoriting this one! I wish it were downloadable!
Mix wise, I would not use nearly as much reverb in the low register, and I would cut the low freqs on all reverbs. Hi-hats can stand to reduce in volume slightly. Snare can come up or be harder sidechained. I also want to hear a bit more snare rattle/high end.
I also appreciate the mix between dubstep/drumstep drums and dnb. This is a juxtaposition I myself like to use!
But I recommend clearing out low end frequencies from most instruments gently in order to make room for the bass range around 200 hz and below, and bringing up that bass. You'll find the power in your track comes from there!
NGADM score: 6.6/10. NG rate for personal preference: 4/5
