Hey man
9 minutes is insanely long haha. It's sounding sweet, though - kick and snare are punchy and audible, mix in general is pretty good. As others have noted, it's a bit repetitive at 9 minutes long, but that's more a symptom of the length than the arrangement necessarily. I really like your breakdown around 3 minutes in, sounds really dreamy! I'm especially a fan of your low sweeping supersaw in that part (3:20).
Overall I think this song would be tighter were it a bit shorter, but you're showing off some good ideas in this so far, so keep it up :)
