This girl has up light on her face, presumably from a flashlight or other artificial source of light. Since it is unusual for natural light to be shining up, this picture takes on a creepy feeling. I think it is interesting that this girl becomes scary and almost threatening just because of the way the light is hitting her. If the light were hitting her face in a natural way, I think my reaction to the picture would be entirely different because she isn't making a threatening face at all.
