Not that I'm so into fantasy art these days, but starting with old, familiar themes for which I created actual artwork in the past gave me a quick comparison to see how Dall E would interpret them. Visualizing the impossible (or seemingly impossible) is certainly a compelling jumping-off point when trying out a new tool.
So, when I began exploring Dall E, a low-hanging fruit amongst my first curiosities was to dive back into deep-sea fantasy imagery, including some of the themes I played with when I began using digital media long ago.

I wasn't very happy with the female characters below, but I was surprised how the same idea turned out very well later when I prompted for the Cirque du Soleil AR-performance capture imagery. Notice how the female figure on the left is bare-chested, yet if I prompted for that it wouldn't likely comply.
The male characters below are depictions of deep-sea trench gods. The idea was part of a series of cartoons I made years ago, so I thought it could be fun to see the idea in a more realistic style. Of course, there are tweaks I'd make if I could rely on consistency (no glowing eyes) but at this point, I'd not gotten into those techniques.
Years ago, I played with making fractal cartoon characters, so I merged fractals, alchemy, and religious imagery - working my way from heroes to jugglers to magicians and sorcerers to demons - to see if could scare the crap out of myself.
My objective was to direct the AI to integrate fractals with the forms of these figures.
