NGAIC -
This caught my attention immediately upon hearing it the first time. Very good Orchestral Drone which fits the theme you're specifically going for, insta-fav'd!. Are you utilising Spitfire Orchestral Swarm for this? There's a few small parts which sound somewhat familiar upon playing this back a few times
As ironic as it may seem to say this based around Particulates: I think there's too much 'air' in the overall mix, possibly from the mic signals (if you are running SF Orch-Swarm, it's a known side-effect of it that I also struggle to deal with). If that's the case, then there's not a huge amount you can really do about that tbh, other than (as a compromise) running those individual sections through careful DeNoising via RX or Acoustica to deAir it gently without compromising on the close & gentle detailing that the library samples are meant for. Or alternatively, very careful shaped filtering above the 10kHz region and then individually boosting-up the most detail-rich frequency ranges on everything else individually.
