Well... that seems to have worked.
The structure is a bit like a Bach Invention. Harmonically it is akin to Hindemith in that it is diatonic but flirts with atonality while still using a key (C Major) to start and end the piece.
Looking forward to thoughts and critique...
I like it! It flirts in and out of tonality as you described. A nice update to an old form -
Really like it!
Thank you both for the encouragement... and happy new year!
