It's the proportions of his face, the lack of a precieved hairline and a elongated forhead makes his head look wierd but totally possible. He also has a squashed face so it adds to the baby look
I'm sorry, but I'm more than sceptical, this is his only post on twitter. I think he only created the usernametousernameto match his manipulated photo.
Like he doesn't look real to me.
