Do you have enough body language and movement? How much do we learn about characters’ intentions and relationships from their physical reactions? What does their body language tell us that they don’t say?
Now, how much dialogue can you now get rid of?
There is always a conflict between what your character says and how she acts.
Characters use their bodies and behaviour to show how they feel about what is happening. Body language is far more were reliable than spoken words when you want to know the truth.
In what unique way does your character move or act?
Is this movement or action is as much a part of your character as the words she uses. So don’t merely listen, but watch the character too.
