There are many ways in which you can revise a narrative, however, I believe that the most important thing is not to be vague - you need to give specific details about whatever it is you are trying to convey in your narrative. You don't want to confuse your audience too much, but rather help them understand your ideas. Obviously, you need to proofread the whole text so as to eliminate any mistakes that might come up. You need to have a clear beginning, middle, and ending, using topic sentences and thesis statement, if it is an essay. Maintain a consistent tone throughout your narrative, and try to stick to figurative language as much as you can,
Hope this helps! :)
