Great ending and chord, something bitter and Mephistopholean, that would capture Hardy's universe. That would have been a difficult assignment to guess.
You've got some fine creative passages in this. Really nice runs too.
The first work of Hardy I read was "The Withered Arm" for a high school English paper.
It is quite a tale. Of his novels, I have read Mayor of Casterbridge, Jude, Tess, and several of his short stories. Jude got closest to me. One of the last stories I read pretty much cured me of Hardy, for although true to his worldview, the bitterest tragedy was all he knew. "The Heart of Thomas Hardy" documentary (include "doc" in the search), an engaging documentary, is on YT if you're interested.
Good luck on the rest of your Hardy journey!
