It would have been interesting to know how much time most people spent per picture because if you look at the quoted comment from the well scoring art interested person mentioned:

"The left column has a sort of door with a massive top-of-doorway-thingy over it. Why? Who knows? The right column doesn't, and you'd expect it to. Instead, the right column has 2.5 arches embossed into it that just kind of halfheartedly trail off."

You can find this in almost every AI generated picture. The picture that people liked most, AI generated with the cafe and canal, the legs on the chairs make little sense. Not as bad as in non-curated AI art, but still no human would paint like this. Same for the houses in the background. If you spend say a minute per picture with AI art you almost always find these random things, even if the image is stylized, unlike human art it has a weird uncanniness to it.

I agree that the cafe had tells, just like the city street. But Gauguin also ended up in my AI bin. With the latter I feel the cropping was very infavourable.

Even though I was warned of the cropping, I didn't think the works would be cut that badly. Since I was working under the assumption that good specimens of each category would be chosen, the cut Gauguin didn't make it.

But in the end I'd convinced myself that Osny also had tells apart from the composition. So what do I know?
