Excellent musical storytelling. Don't be afraid of length if the piece requires it. I've just worked out that my average track time over my favourite 24 tracks is 5:55, with the shortest being 3:50 and the longest 8:16. There's lots of recorded music out there which range from over 8 minutes to over an hour long, not counting classical. I enjoy listening to long playlists with headphones on, so when I'm in the zone I really love to flow with longer tracks.
My only criticism of "Sundown" is that it would have sounded more authentic if Carol could have sung with an American accent ~ though I allow as how I reckon that don't make no never-mind.
