You beautiful bastard.
You suffer from a problem I had and fight against. Space, length, expression. I used to post 8 minute tracks all the time, you want to generate an atmosphere draw the listener in and take them on a journey. Completely get it. But what you have done in 8 minutes can be tightened to 4 minutes with no loss to the casual listener. I absolutely know your why and how, I love drawn out ambient. But most people are not going to sit and listen.
I love everything about this track, it's resonate, spacious, meditative. I would love a glitch beat on this, low in the mix and sparse but enough to propel it forward. I would be slamming reversed reverbed guitars all over this playing dissonance and harmony, really toying with the balance.
It's well mixed, but your reverb is resonating the low end causing some muddiness, just drop the low end of it and you're grand.
Perhaps add some harmonic vocals. attempt some additional tones, a cello would do well. Keep it simple though.
I always enjoy your music, this is no different. All my feedback is just what I would do.
5 as always
