Well done. You definitely caught the feel that you intended.
The ending notes were perfect, simply coming to a stop. While it didn't cut anything off in a technical view, it ends the song wonderfully after establishing a pattern, the breaking that pattern on the final note. It feels very definitive and abrupt, especially after the strong reverb throughout. I can see the main character in this reminiscence walking away into a field of dull, ash-grey as the camera pans down to see an item of personal significance resting on the ground.
The strings felt a little strong when they first enter the piece. The rhythm that leads us through the entire piece are almost drowned out for a couple of seconds. But that's the only criticism I can really make. A fine piece of work and a beautiful piece of art.
