Write a reflective piece analyzing the writer's own choices -- which narrative tools were used, which was hardest, and what would change with more time.
A craft reflection is a piece of writing ABOUT your writing: not what happened in the story, but what choices you made as the writer, and why. Professional writers do this too, often called an author's note.
Answer specific questions in full sentences: which of the four tools do you feel proudest of? Which was hardest? If you had one more week, what would you revise further?
Mastery looks like: They write a specific, honest reflection naming a particular craft choice, a real struggle, and a concrete idea for further revision.
Common stumbles: Writing only vague praise or vague complaints without naming a specific sentence, tool, or reason.
