Opinion and critique on thesiss statement requested! (English teachers/majors prefered)?

First off, don't complement the author or the work in your thesis. Second, the book's themes are obviously vital in developing the novel. (If you are going to keep that part, it should "book's.") My AP English Language and Composition teacher told us to list it out, so I'd keep that. (Considering that all but one of us got fives, I'd say that she knew what she was talking about. [The person who didn't get a five, got a four.]) This sentence, though, implies that you're going to tell us why these things are important, while the summary of your paper says you're explaining them. I would change it to "Oscar Wilde uses imagery, syntax, paradoxes, and symbols to develop the novel's themes of..." and then say whatever the themes are.
