Sister's Angel Picture

Jill sent us this angel picture of her sister. Is it an angel? Look closely to see the angel face on the upper right side of the picture:

"I have another interesting picture for you. This picture was taken of my sister, the only thing is that you can't see her face. If you look to the side of her face you can see an angel's face coming through her and on the sides of her head you can see the wings. What do you think??"
