Book Report: "The Casual Vacancy" by J. K. Rowling. What would you choose to analyze?

Hi book lovers of Reddit.

I have read J. K. Rowling's new book "The Casual Vacancy" and now I have to make a book report about it for school. I have to include: "A discussion of RELEVANT stylistic characteristics (e.g. use of imagery/figurative language, use of dialogue, minimalism, composition, narrative perspective, etc.) You may of course include other aspects of your novel as well according to your own judgement."

Those of you who have read the novel. What would in your opinion be most interesting to analysize and write about?
