I got 17 out of 20. I pegged the bezerk drawing as generated because the bottom part of the armor lacked symmetry and didn’t make any sense. I got the other three line drawings incorrect.
I have spent WAAAAY to much of my freetime generating images and apparently have picked up an eye for the weird types of artifacts that these generators produce. The hardest one to articulate is that generated images have a very specific type of noise. Images create a very nice grainy type noise while digital images get more of the blocky jpeg artifacts and banding. Generated images get this weird hybrid of the two that isn’t consistent across the whole image.
