Good lyrics, expressively sung, good mix.
To re-use the adjective that others have said:
beautiful.
As for suggestions, the "wall of strummed guitars" doesn't let up. It might be better to drop them out completely and points, and change the instrumentation. Similarly, your lead acoustic is great, but on the last verse it feels like it's trying to get attention instead of sitting in the mix.
Or you could ignore the above suggestions and be really rightly pleased with what an excellent job you've done!
