Nice work on this, I enjoyed listening to it.
I could only really pick out a couple things that bugged me. First, I think the synth that comes in at 0:43 is a little too loud. Aside from turning it down a bit, I would probably try putting some kind of chorus effect on it so that it sounds less mono, if you get what I mean.
Second, I thought the kick lacked impact (albeit only slightly). I would be curious to experiment with a lower-pitched kick, or if not, maybe layer it with some other kick. But far be it from me to shit on your creative decisions.
Good things that stood out to me:
-Nice composition
-2:22 has a fucking nice atmosphere; same with the ending. That square thing with the delay effect is fantastic and well-suited for this song
-The thing with the kicks at 3:15 is cool
-Enjoyable song as a whole. If it were mastered to a professional standard (not to talk shit), I could see myself listening to this a lot.
After listening to this and Antare's answer multiple times for reviewing, I'm wondering if you've ever considered making an ambient style tune? You seem like you'd be good at it. Also, how many hours went into this?
