Ran through some of my relatively complex prompts combined with using pure text prompts as the de-facto means of making adjustments to the images (in contrast to using something like img2img / inpainting / etc.)
Great question. I haven't tested the creation of such an image from scratch, but I did add an adjustment test against that specific text-heavy diagram and I'd say it passed with "flying colors". (pun intended).
Funny how it changed the spelling in the Magic coloring book. Westher, wntility, substittutesfor, yyears. What's worse is that it removed the CO2 tank and changed some vital numbers, eg 8' to 3', completely altering the meaning of the schematic. Not what i would call passing with flying colors. Still pretty cool as a party trick, like most other AI outputs, useful only with careful review.

It's definitely impressive though once again fell flat on the ability to render a 9-pointed star.
