Well, most of the pictures (if not all), while astoundingly good as an idea, have the tell-tale signs of being AI-generated, the kinds of mistakes a human would never make.

For example, looking at the WALL-E one [0], you can clearly see that the hands and feet aren't actually separated properly. There is also plenty of missing "logic" around the armpits. These are the kinds of mistakes a human can't make - especially one that is so adept at drawing the other parts so perfectly.
