Here’s a working thesis with potential: you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal. Your reader is intrigued but is still thinking, “So what? What’s the point of this contrast? What does it signify?” Perhaps you are not sure yet, either.

Then, define the subject of your writing clearly and construct a statement that depicts precisely what you hope to show about this subject. Throughout your essay, you will be looking to the art itself to provide evidence that supports your underlying analysis.
