This is lovely playing as always David, and again, a dark/warm "American" sound from a great vintage Baldwin such as yours (I suspect would sound good on a Mason Hamlin as well) does the piece justice.
I hear glimpses of Gershwin here with pops of more tonally provocative spots dispersed throughout, I liked it a lot.
I have a hard time suggesting much in the way of things to 'improve' or look for, however my only though is that within the texture and your phrase planning, perhaps trying to find ways to emphasize those spicier harmonies more, maybe a little accent, or tenuto, or slight cresc into them with a backing off in the resolution, std stuff you might do in a Beethoven or Mozart work where more complex harmonies highlight opportunities for more emotive playing, but this is a minor 'taste' suggestion and not suggesting your piece was lacking, it just something I might try to look at.
I'm working on a prelude at theme moment that's almost done and these are things I'm trying to apply given some similarities in the work I'm prepping and this fine one you presented thanks for
sharing.
