One fascinating feature of these generators is how phenomenological they are. The entire outfit is near-uniform black. But just with different frequency in the lighting, you can make out armor, leather, and cloth. The wrinkles on the hood are almost tactile. You know what that material would do, sliding back over the helmet.
Human artists take ages to convey that sort of thing, even if they could dream up and sketch out this image with one-bazillionth the amount of training. They're gonna make all the fiddly little details symmetrical without even thinking about it. But it takes ages to draw a white shape with some black blobs inside and make people's brains go "this is gold."
