Does my narrative fulfill my purpose? Will it entertain my reader?
Are my characters interesting? Is my plot clear and logical?

What kinds of stories does my audience like?
Will my audience enjoy what I wrote?
Did I choose words that tell exactly how things look, how people feel, and what happens?

As an expert, I would say that these are all important questions to consider when evaluating the effectiveness of your narrative. It's important to have a clear purpose and to ensure that your story is engaging and entertaining for your intended audience. Your characters should be well-developed and interesting, and your plot should be clear and logical. If your story is meant to teach a lesson, it's important to make sure that lesson is clear and easy to understand.
Understanding your audience is also crucial. You should consider what kinds of stories they enjoy and whether your story will resonate with them. It's also important to choose your words carefully to ensure that you are effectively conveying the emotions, actions, and events in your story. Finally, it's important to consider the point of view from which your story is told and whether your audience will be able to understand and connect with that perspective.
