It’s the perspective. The photo was shot from somewhere above — that foreshortens the body, and makes the head appear larger. (That’s not proof that the photo is genuine — but, if it’s a fake, it’s a good one.)
“Its the perspective.”
Normally, I would agree with you. Perspective in pictures and I don’t get along real well.
However, her head looks normal, why wouldn’t his? The picture looks like it was shot pretty much straight on by someone about the same height as 0 - if that is indeed him.
I also am not saying it’s real or faked, it just looks odd to me. Just like everything else that is associated with 0.
