What style of writing will you use to tell the story? How is the character reflected in the style and through the POV? How is the story problem reflected? This is important because it will help us invest more deeply in the story so that we will be seduced into learning the things we need in order to “survive.” In TO KILL A MOCKINGBIRD, Scout's spunky voice can engage the readers, drawing them into the story without hitting them over the head with a theme or didactic message.
Think about style elements that seduce the reader into the world of your story. Is your voice fresh and natural and uniquely yours? Does it reflect the tone of the story? Is your imagery sensory and rich and do you avoid cliches? Is the POV you've chosen the best one to convey what you want to your reader? First and close third are most common and share similar advantages. But don't be afraid to mix it up, as long as you are clear and consistent and be sure not to change POV's at random, but always for a reason. Are your sentences smooth, do they flow, is your syntax correct? What about your grammar? Do you have a natural rhthym between description, action, dialogue and interior thought? Some of these things can be improved in your second and third drafts but you should have a sense of your voice right away. Try to write in the voice that comes to you naturally at first. After a few chapters, take an objective look and see if the voice is working. Analyze what works best and what isn't as successful and then put conscious effort into tailoring the voice as needed.
