James,

Always a fun idea to experiment.

A pleasant progression. Mix is good.

I don't much care for all the fast note runs that the sax does (I was going to say "gyrations").
That is, of course, a personal opinion.
I thought it needed to "breathe" a bit - which it never seems to. That is often the case with BIAB soloing, but if you regenerate (many times) you can usually find enough variation to get what you want/need. That being said, perhaps this IS what you wanted.
Also, I did not hear any kind of "theme" to the soloing. Just random soloing. Creating some repetition would help that.
Opinions. You know what they say about them...
