First of all, 2012 does not qualify as an old song around here. Dredge up something from 1999 and post it. :)
Nice tune, vocals come across well. I think the mix had a lot of upper end sparkle, and maybe too much in spots. You might try the piano eq'd with a little lower eq bump? On the other hand, the piano is super clear in the mix. Maybe duck it a little when she is singing?
I think you need more tasteful lead guitar noodling in this. Just in spots.
Linda Ronstadt/Carly Simon/Carole King are some very favorable comparisons I could make, nice composition here.
cheers,
