Bob,

Nice melody. Xtina has a cool voice (very "today").
A lyric sheet would have been nice. I had some trouble following the narrative because I lost some words here and there. Part of that was due to the bass crowding the vocal occasionally.
The Bass has good punch. In my monitors it had too much bottom. In earbuds it was better (but you might want to roll off the bottom a bit).
Drums sound great.
The build is nice. Cool steel. I think there is a bit of banjo towards the end? ...it was really low in the mix (or maybe I'm just "hearing things").

I thought that the vocal (and BGVs) could use a touch more reverb (the main is especially dry).
And the BGVs seemed louder than the main vocal when they piled up.
