Think of your manuscript as a canvas. A painter steps in front of a canvas to craft a painting. That painter uses different brushes, different colors, different techniques, even different kinds of paint to create her/his art. This is how I think of writing. Same thing–the writer has different tools at her or his disposal to tell a story. That writer can use dialogue, back story, conflict and plot, world building, body language, action/reaction and any number of devices to tell a story. When I’m reading submissions, I’m looking for balance. No one is getting a rejection simply because paragraph two on page three has too much dialogue. Rather, the overall storytelling in the first five pages is what I’m evaluating.
