Brad,

This is nicely done. A lot of good stuff going on.

Vocals are nice. Harmonies, too.
Good job on guitar and bass (the bass gets a bit repetitive, but that's Country for ya...)
Nice snaps.
A good mix.

A couple of suggestions -
The harp and fiddle are good additions, but... they are both "busy" tracks - so the combination of the two gets really "busy" (and get-in-the-way of the vocal at times). Having them alternate turns would take care of most of the busy-ness (but you might still want to drop them - or at least parts - when the vocals are happening).
The snaps are nice, but I thought the song was beggin' for a drum track to join in later in the song. Could be just the last verse (stick) and chorus (snare) - the Nashville Even 8 would be the obvious choice.
Again... just opinions.

Keep 'em coming.
