Somehow the sidechaining at around the 3:38 mark seems off-beat from the actual track. Maybe try tweaking it a little bit. Also, the piano at ~4:03 sounds a bit intrusive and doesn't sit the best in the mix, but I bet if you EQ and/or level it in a nice way it'll sound really good. The buildup is honestly so great though. Good stuff!

I always enjoy listening to your stuff, especially as it progresses further and further! One thing that came to mind as I listened from the beginning is to make the transitions a bit smoother. What I mean by that is as one example when the big chords come in at 1:00, it feels sudden. I noticed a bit of hi pass leading up to it. Maybe remove 4 kicks before those chords come in, add a bit of a break beat or some sort of cut. Also think about exporting the chords with a ton of reverb on them to get a huge tail, turn it into audio, reverse it, and have it fade in subtly so it doesn't seem to come out of nowhere. Surprise can be a very good tool if it is used right tho!

You definitely have something special with this breakdown. Love the ambiance you've created. Heavy drop. All around dope.
