I would say it is a good book review. You described what happened in detail and I was able to picture the events of the book. However, I would change your answer for the theme. A theme is the moral of a story. For example: "Don't judge a book by its cover," or "All actions have consequences." So find a theme that best fits the story and you'll be good.
You may meet a person and instantly know that you will be best friends forever. Other friendships develop over an extended period of time. In some friendships you may feel a sense of equality, while in others there may be a clear sense that one is giving more to the friendship then the other. There are no rules about how a friendship has to be. If you are able to share your life with another human being, by all means go right ahead. All friendships are unique and special in their own way. Each one is valuable.

Answer:
In the poem, the Duke is very overprotective of the paint, when he declares <em>"since none puts by The curtain I have drawn for you, but I" </em>meaning no one will touch it but him. At the same time, he is using a lot of details about her dead wife and shows his jealousy when he says <em>"not Her husband’s presence only called that spot Of joy into the Duchess’ cheek" </em>she was too kind with everyone, not only with him and he wanted to be the only attention of her, "<em>She thanked men—good! but thanked Somehow—I know not how—as if she ranked My gift of a nine-hundred-years-old name"</em>. In that phrase, he claims to be an important figure.
He seems overly proud of the paint, but with more interest at the end of meeting and marrying a new woman <em>"Though his fair daughter’s self, as I avowed At starting, is my object. Nay, we’ll go Together down, sir."</em> The poem shows that he was not a nice man but superficial and depreciable.
This sentence is complex because it contains both a dependant and an independent clause. Do not be fooled by the addition of "however" or the length of the sentence.
If you need reasoning, here you are:
Simple: has one independent clause
Compound: has two independent clauses (either joined by a coordinating conjunction or a semicolon)
Complex: contains a dependant and an independent clause
Compound-Complex: Contains at least two independent clauses and one dependent clause
Hope this helps! If you have any questions about what any of the words that I used in my explanation mean (such as an independent clause and a dependent clause), feel free to ask.
