To get these results I fed Midjourney almost 600 names and techniques using the same prompts: by [artist name] --ar 9:16 or [technique name] --ar 9:16. Those results that showed distinct style went into this list.
This list is random. The categories it's separated into are subjective and imperfect.
The styles presented here might not be similar to the techniques of the actual artists. To be honest, I don't care. More importantly, these names and words alter Midjourney generations in a distinct and reproducible way. Which might give you the foundation upon which to build your own amazing prompts and get your own unique results.
