Post this under the Notebook section if you want people to correct it! Then people can highlight mistakes, etc. Hope this helps. Otherwise, here is how I would write what you wrote while trying to keep it as close to what you said as possible:
I wrote my opinion about my favorite book in English. I am writing such an article for the first time.
I like reading books. One of my favorite books is "The Shawshank Redemption." The main character, Andy Dyufreyn, plays an important role in this book. To be fair, I should say that the movie is better than the book, which was written by Steven King. Young Andy is accused of murder (and sent to prison), but he didn't do it. (There,) He is tortured and bullied. However, Andy becomes smart and finds a way to escape. I love this book and would highly recommend it.
Hope this helps!
