Nice! I see a lot of names I recognize on that thank you list :) I love the community here.
I'm appreciating what you're doing with distortion in your intro, nice and cinematic. I think when the lead comes in at around 30 sec it could be panned around or pingpong delayed for effect. It and the distortion are quite bright tonally and stand out from your bass in a way that's not quite what I would expect.
The sidechain makes up for it some, but overall I think your side chain elements, lead, and bass, are too loud for your snare to cut through. Overall good chords through here and varied instrumentation.
At 2:07 that sax sounds a bit clumsy, the bari. It's very verbed out through here, we lose sight of the bass, and I can really hear how loud these are when we have them alone with the house bass/kick/hat. That bigroom kick should take up a lot more space!
I would take down reverb here by a LOT. But I praise the vision and the cross genre work, as well as your consistent theme.
This track shines in its variety and sticking to a theme. The reverb is really hurting it by a lot as the low end shoegaze wash is muddying any limiting, compression, covering up finer areas of mix.
Really though, I find your writing to be a treat. The kick at 4:39 could be tuned to follow the bass line so it doesn't clash with the bass. On the minor i chord it does fine but otherwise the sub clashes with the ... I forget what to call that chord oh well.
Otherwise, really enjoyed the track. Outro section was a pleasant departure there. Watch for clipping at 6:29.
My advice, mix at a quieter volume and keep things clean on your eq. Watch for frequencies below 250 hz on non bass instruments. They will get in the way of bass. Sidechain is your friend but will not fix all mix woes. Snare and kick should be loudest parts of mix, followed by lead and bass. The rest is to your personal taste as long as hi-hat and crash are not sticking out. Beyond that, reverb wash can be turned up on a long cut off or transition and back down for the rest of the track. It can even be sidechained on big sections, mind you. There is so much one can do for clarity.
Best of luck in all your future endeavors. Thanks for coming out to NGUAC!
