Accordion to me, you did a pretty good job.
Did you fix the bass guitar? Sounds fine by me, and as mentioned, bass isn't really featured in this type of music anyway. You just have to hear it a little through the jukebox speakers that you are crying on as you lean on it. :)
I think the mix sounds pretty darn good! I'd bring the kick drum up as others have said,
and less reverb on the vocals (but overly reverbed vocals are a staple of the genre here - I'm thinking late '70's c & w)
The thing that started bugging me was the omnipresent and uni-volumed hi hats and cymbals, I think if they came down a bit, it would bring the vocal out front some.
Those are all just niggles anyway, it sounds pretty together as it is. Good one!
cheers,
