What a nice listen and change of pace --- at least for me. I can imagine this song taking another with more volume and build, synths roaring in and out, etc. However, I think that you have hit the nail on the head with what you have done. I thoroughly relaxed when I heard this, and after the day I had ---- well, it was just what I needed. The volume was a bit low but that would be all I would change on this.
Good job!
