I love that the melody has this bittersweet tone to it that says, "it's over, but that doesn't mean it was for nothing" which is very pleasant to listen to. The acoustic guitar also gives me the idea of resting by a campfire now that it's sunset.
Personal preference but I think removing the very last note would give it a much more fitting "journey's not quite finished" ending. Going to the tonic feels to final for me, I'm not going to dock points or anything for it, still a masterpiece either way :)
