Don't be second guessing yourself and start messing up the mix..... I have a tendency to do that too.....looking for perfection but that's not necessary.....a good song shines through the nits and warts of a mix.
If I was going to do anything to the mix I'd shorten the intro but aside from adding some sparkle.... the total silent break at the end of the intro was a bit awkward sounding.... that's about it. Everything I'd change is pretty much right there in the intro.
Great song.... but you already know that. Listening on cans..... yeah the vox are a bit hot..... not overly so though.... they make it easy to hear the words....always a good thing in a country song.
Of course you know me..... I'd do a few things different in the mix but that's not even important.
