Even with this hand-picking I got 70% and am nowhere near an expert on either AI or human art, having dabbled in it for a day or two back when DallE and Midjourney first became popular. I'm sure someone who's into the image generation field could score 80%+ consistently even over a larger dataset just as handpicked as this one.

Telltale signs of AI:

- Cliches. "Punk Robot" is a good example, a human artist capable of creating that would've somehow been more creative. - Obviously facial expressions and limbs are telltale signs, very uncanny valley - If there's an accurate geomtric repeating pattern, it's extremely unlikely to be AI. Something like "Giant Ship" is afaik still practically impossible to generate. - Weird unfinished parts of a world. See "Leafy Lane". Why is there a vantablack hole at the end of the road? It's not physically impossible but it makes little sense and a human wouldn't put it there in that painting.

Likewise I was at 70% and am by no means an expert on art. Although I do generate a lot of AI art for my work
