Anna's Portrait of Daddy

Last week they had a display of the area kindergarten's student's portraits of their fathers. Here is a picture that my daughter made of me. What seems to happens is that Anna watches her neighbors make their artwork and she does the same.

Anna seems to be getting that Daddy looks different from the other dads but still, in the portrait, I have black hair, brown eyes, and have not shaved.

This above is one explanation, the other is a mystery. When I ask my wife for an explanation, this is her look.
