In my experience, GPT writing/prose is generally fine if you move past boilerplate instructions. Pasting a large excerpt of text you want emulated is smoothest. More targeted/specific words/instructions also work. But it's hard to know what those words might be. Pasting an excerpt and asking GPT what words describe the passage clue you in.
