Grats on tackling super-challenge. Liked the organic rhythm patterns.

I think, one of the instruments could use softer attack/release though.

The manipulations of the tempo feel very organic. The build-up is satisfying. I also really enjoyed the instrumentation: the timbres blend very well together. The fact you selected instruments with unaccented onsets was a very good idea, as it allows your track to be reversed and to still sound the same. Solid entry!

Cool stuff, like the experimental rythmic pattern and movement. good job.

I like that there is a literal moment of silence in the middle. Clever. Love the drone and heartbeat. Great work.
