This stage resolves issues over the clarity and flow of your sentences. It could involve moving the sentences around to clear up your narrative but always aims to preserve your voice in your work. If your sentences feel formulaic, with excess adjectives, the vocabulary is unsuitable for your audience (strong language etc.), if you have used specialised jargon without clearly defining terms, or your transition between paragraphs is disjointed, it might be a good idea to request a stylistic edit.
