Interesting minimal piece.
I think that the overlaying sounds and synths work well. There is a build-up and progression in them with these synths seemingly panned in the right way. I like the tiny changes which you make throughout the whole song to the synths and effects.
Although I would suggest to also make tiny changes to the repeating clav/vibe like sound with which it starts in the beginning, when listening to this on loop it doesn't seem to work well with the repetition of the same tone without any changes to it, so perhaps something like panning with a low-pass effect or something else might work to make it a bit more interesting.
