Really nice song Lynn! I like the thick harmonies that come towards the end. It would be nice to copy and paste them towards the beginning in the some of the chorus sections too.
Some type of melody on the opposite pan to counter the sax line might balance the sax a bit more.
Having the sax cut out in quieter sections and come in again is also an option.
Reminds me of Steely Dan and Pink Floyd. Great work! :)
