Ahhh, I get it now
Your form of ambient music is introspective repetition of sound. You pulled that off almost perfectly with the FX changeup on the main instrument on this track, just needs a bit cleaner FX flipping so there's no jagged edges between the FX masks that sound like hard stops. Next time instead of applying the different FX at different time intervals on the mixed down instrumentation, do a new copy of the instrument for each FX you want to chain. So, if you wanna do a stereo pan and phasing FX, then a clean FX, then a low-tone EQ and muting FX, do three copies and cross-fade them at the crossover points with about 2, 4, or 8 beats of crossover so it's almost unnoticeable. Otherwise, this was a great piece.
