Tip #167: A question of logic

Ask yourself “logic questions”... they’re one of the first things pitchees and potential buyers ask. Logic questions are about internal consistency and world cohesion, e.g. “Why is the monster attacking this specific town?”, or “Why does she agree to marry him when she’s shown to be terrified of commitment?”, etc.

Tip #4: Why trees are important

New writers will often say that “The trees bunched together, casting deep shadows over the lonely trail.” Well, there are thousands of kinds of trees. Do you mean pines? Then say pines. Or did you mean coconut palms, or willows, or eucalyptus? Each type of tree creates a very different image. If your character is being chased by a “pack of dogs,” for heaven’s sake, tell me what kind of dogs I should be imagining. Are you talking about wolves? Dingoes? Mastiffs? Hounds? Tail-wagging Chihuahuas?
