yeah, but is there a certain thing you have to do? Like are you writing about what he did in the book, or his character traits, or your opinion on the character? Or all the above, meaning it is generally about that character, in which case for the article i would use all the ways i mentioned (if im understanding what you need to do though)
When i do these things i break it down to three things (usually it is in essay format so you need approx three idea's anyway) the opening paragraph has to say what your doing, the three things, and some sort of a carry along that ties it not only to the final rap up sentence but also to each main idea/point in the body paragraphs.
