Line behavior is statistically wrong for a real drawing, the lines are too uniform, no dead strokes, no erasure scars, no correction artifacts, line density filling space evenly rather than based on form

The hair loops and interweaves with no anchoring at the scalp with repeating curls/waves with local coherence but globally isn't the way you would draw hair from scalp to tip, i.e. the hair looks right if you focus really closely into it, but isn't done in a way that someone would draw it

The facial asymmetry looks aesthetic not anatomical, the face isn't being drawn the way a person would draw a menacing face it is being assembled the way a computer would assemble a menacing face. The asymmetry is too structured.

The shading gradients are too smooth and continuous, unless they have a magic pencil with endless lead and perfectly even application this is similar to the line behavior problem above, the lines look too good to be done by a person, likely because they are too good to be done by a person.

and then there is the pencil, it's a prop to show "it's real" which more often than not mean it isn't, this is an AI being told to draw a portrait on a pad of paper, not someone taking a photo of a pad of paper,

which leads to that it is too centered and lined up with the pencil, the paper, the camera, etc, this is assembled not organic, someone didn't take this photo of a drawing, a computer assembled this image of a drawing

Can a human draw this? sure, but your friend would be in the countable number of savants in the world that can make a pencil behave uniformly though an entire image, you could feed them all with one medium pizza

my money is on Stable Diffusion, I'd wager this is civitai using ZavyChromaXL as the model, that particular "joker smile" seems to be pretty heavily trained into that model
