Lynn,
That is one fat mix...dripping with blues! The volumes, pans and space are all excellent.
There are two things I would do if I were mixing:
1. add a tiny, and I mean tiny bit of reverb to the snare...use pre delay so that it kicks in after the snare hit.
2. on your vocals and guitar solos in some places you are right on the beat...I would nudge them back ever so slightly so it sounds like your playing behind the beat...like the old jazz cats.
I love the tune, I love your vocals and I love the guitar work...that organ is sooooo fat too! Great job!
