You have a wonderful voice! Much cleaner than I could do it!
Now, I almost feel that this needs a bit of compression overall, and your low end sounds empty (though I'm listening on computer speakers at the moment). If you've got some bass going on in there, it's completely left out on less bass-rich speakers. Try boosting mids of your bass to fill out the soundscape.
But it's so nice to hear someone playing old-style. Reminds me of 50's sock-hop tunes! Very nice!
