My game is looking at the eyes, seems like the model has a tendency to make faces that have pretty much mirrored eye shapes and sockets, pupils being clear of imperfections or just plain circles or even both pupils being identical to each other, tilt is also a huge issue, most of the AI images have their output "looking directly into the lens" and nearly perpendicular to the aperture, real humans are off center in more ways than one in all of these aspects and more, as well as having numerous orientations
To me, looking at the background is kind of cheating to sus out facial features, after all we are trying to figure out if the face is real not the background
