When you are editing your work think about what you want your readers to feel at different points during the story? How do you want your reader to feel when they finish reading?
How do the characters in the story feel about what is happening? What type of person is your character? What would he or she would do when faced with the situation you're writing about? What's your characters body language like when they are happy or upset? Are your descriptions consistent and believable.
