I'm a big fan of experimental music
and i think you have stumbled across something nice here. However i feel it lacks structure or movement and that leaves the piece feeling fairly static. I think adjusting the volume at parts or perhaps adding some percussive element unreversed could be nice. A vocal sample over the top could also be interesting if you could find someone talking on the right subject matter. Anyhow i like what you've done and this song shall have a place on my local library.
