Significantly simpler scenery. I'd put only the first at good complexity/quality.

2nd is quite simple, but still suffers from your typical lighting issues that plague image gen. (shadows are significantly off)

3rd has magically appearing spoon and isn't that complex.

4th has a lot of prompt following issues

Some others feel quite off -- wizard, flying dragon, etc.

Still impressive of course, but not to the degree of what I saw on the marketing page.
