Good song. Needs some fillers, i.e. Fiddle, steel guitar, etc... What is there sounds really good. Might bring up the drums a bit. Might bring up the vocal harmony a bit too...
My only crit of what you have at this point would be in the vocal diction. In some places it sounds like the words don't flow in a easy country style. Best way I could describe it is as perhaps someone who doesn't speak or sing in a southern accent normally.... The vocals themselves are very good, intonation is great, in tune and a very pleasant listen. Not commenting on the singing....I think the singing is fantastic.
Anyway, really good song and what you have here is really a solid production.
