I saw an odd promulgation when I specified the first of two characters as "Asian" and the second simply as "blonde". The blonde characters, as I generated more images from one prompt, took on an increasingly Asian aspect. Even when I added "Caucasian" to "blonde", both characters appeared Asian.
Okay, ethnicity and coloring are not exclusive categories. Still, I specifed mutually eclusive criteria only to get the same results. It was not until I deleted "Asian" that I regained control. And this did not happen when I specified "Black" for the first character alone.
Through enough iterations, though, the LLM will swap criteria between characters, add or distort figures and change the value of alternatives in drop-down lists. Its attention wanders.
I shouldn't wonder. When config.sys was a thing, we assigned the keyboard and mouse to INT6 and INT7. Even then, we humans were the slowest of external devices.
