Agreed. For the image that was obviously an emulation of Guts from Berserk, the only reason I called it as AI generated was because his right eye was open. I don’t know enough about illustration in general, which led me to guess quite a few incorrect examples there.

I found the photos much easier, and I guessed each of those correctly just by looking for the sort of “melty” quality you get with most AI generated photos, along with intersected line continuity (e.g. an AI probably would have messed up this image where the railing overlaps the plant stems; the continuity made me accept it as real). But with illustrations, I don’t know nearly enough about composition and technique, so I can’t tell if a particular element is “supposed” to be there or not. I would like to say that the ones I correctly called as AI were still moderately informed because some of them had that sort of AI-generated color balance/bloom to them, but most of them were still just coin toss to me.
