Been fiddling with random prompts from an article I was reading and trying them out in SDXL on Clipdrop. Just a few samples:

Alien planet prompt using the Cinematic style filter on top two. Then I added people -- those first guys were more or less random -- and switched over to Fantasy Art for the rest.

Think that last one has finger issues. Will probably fix later, keeping a few in reserve for gallery work.

Base prompt using Cinematic style: Sci-fi digital painting of an alien landscape with otherworldly plants, strange creatures, and distant planets

Modified to these in Fantasy Art style:

Alien princess with wizard in an alien landscape, exotic plants, strange creatures, and distant planets

a beautiful princess in garden on an alien planet with otherworldly plants and creatures starry sky, distant planets

Not sure how they'll work in MidJourney or elsewhere and I haven't used them on my local SD install so cannot say how good for other apps.
