Today, I let myself play with Midjourney again, and it FINALLY started giving me what I wanted for Nik, the prince who prefers to be recognized as a doctor and who has the skills to be respected as such. The face isn't exactly what I'd imagine, but it's pretty darn close. You'd be amazed at the subtle changes MJ makes with each iteration. His was a tough one to pin down--I've tried on several different occasions since I started playing with MJ--along with a gray and red uniform that was anywhere near what I had in mind for his work as a medic on an Ethalian starship. Like with Ann's armor, this uniform isn't perfect but it's pretty close, maybe even better than what I could have imagined. (When I "see" my characters, it's not actually as specific as readers may think. I generally leave a lot for readers to interpret for themselves.)
Overall, I'm pretty satisfied with this, except for the eyes. It's a glassy stare like they're zoning out.
But, I have my Lord (and doctor) Ivandru Nikkolas. He has a princely charm about him, wouldn't you say?
ps--I still prefer actual artists. This AI is hard to work with and leaves a lot lacking, even as I learn to use it more effectively.
