My goodness! I love the texture of the canvas, and how it makes the redness of Harry's spanked cheeks look like they are raised a bit. And the tree: it gives the tree such age, as if it's witnessed this before, and the bark has a special spot for lovers to rest.
The way they are entwined gives the picture so much emotion. There seems to be a cleansing catharsis going on as well as real lovemaking.
Well done! (And I can't wait to read the story by joanwilder, too!)
