Judging from your other tracks I've listen to, you enjoy a slow build up, starting very sparse. Which is really cool actually! I guess I feel like there's A LOT of mid to high end stuff going on for the first 2 minutes, and very little low mid to lows. I think even just a nice dark verb would add a lot for me. Just give it a smoother, fuller, and warmer body to every thing. I know Kalimba's can be really harsh and tiny, because they're just small tinny pieces of metal. That with the filtered drums just adds up to me wanting just a little bit of something down there. Maybe those background sustained chords could've filled that in if they were louder or eq'd a lil different, dunno. Still great ideas and work! Just some constructive criticism on what I would've personally done different.

Cool ideas. I think the second, fuller section sounds great! That ostinato guitar part that plays through out the whole song is maybe a little iffy tuning-wise, but maybe you wanted it that way. I think I would enjoy that first section slightly more if it had a bit more fullness or "juice" to it, like the second section does. Cool stuff though! I like the mixing of genres, keep being you.

Still don't know how you make these. There's obviously some slowing down happening, and that may contribute to the length of them. But it doesn't sound like the whole track is just slowed down, some instruments sound more normal speed than others, like the piano. Like do you write 6 hrs worth of this stuff, or is it improvised? Or both? I can't wrap my head around these, though I may be over thinking it. They all sound great though.
