Read over the text and find details that support the arguments you are trying to make in your thesis. In a critical analysis you are able to assume the reader is familiar with the reading material. As the writer you use quotations and references to the text should only be used to support your viewpoint and help with the thesis.
Start writing the first draft by writing the introduction that will explain what you are writing about and end the introduction paragraph with the thesis statement. Each of the following paragraphs should prove the thesis statement you have made and end it with a conclusion statement that restates the thesis and keeps the article together.
