How do we do this job?

Hello everyone. I'm an author of erotic short stories. I'd like to create visuals and perhaps even turn my writing into comics/manga. I have absolutely no idea how to make images in this style. Gemini and Chat GPT are out of the question. Would you be so kind as to explain it to me or tell me what resources I could use?

Here's an example of what I'd like to produce. Perhaps this isn't the right place to ask the question.

Thanks.
