Describing Your Character
Describe your characters from the POV of multiple other characters. Knowing how others see your character can help you as a writer in defining him.
Describe your character without mentioning her hair or eyes. Think like Sherlock Holmes. What would Holmes know about your character just from looking at her? What about her appearance gives clues to her personality? Is there anything distinctive or defining about her appearance?
When this method really came home to me was as I was describing my MC’s little brother from an outsider’s point of view. He noted that the little boy had a skinned knee and red scratches on his arms, the kind you get climbing trees. That defines the little brother so well in just one line. Why can’t I do this for my main characters? So I set out to try it.
