A collage! This must be a week of kindness.
Good eye on picking out that odd shaped mechanism and blessing it with symmetry. The background is a bit bland, but perhaps it's best to let the foreground forms do the visual communication. Neatly done, Artist.

I absolutely adore this pic!

The elements are chosen perfectly and the overall composition and feel are super strong. I would be proud to have this as a cover for the story (and would feel a little guilty too, as the picture is much better than the story itself).

Might be my bias, but this is absolutely my slate topper.

Edit: Would love to learn about how you found the right clip art and how you created this.
