I agree that the majority of Glo-Glo's photos look uncomfortable and overly posed but I'm not sure if that's fear in her eyes. When I look at her photos, I don't see any recognizable emotion in her eyes; it's almost like looking at a mannequin or a statue.
When we smile, we subconsciously go through a series of facial muscle movements: the corners of our mouths rise, our cheeks elevate, our eyes crinkle slightly, and so on. (It used to be called a "facial flash"; think of the face you make when you meet a friend you haven't seen in a while.) In both of the photos that were posted, even though Glo-Glo looks to be smiling, that smile stops at her mouth. Cover up her mouth and tell me if there is any recognizable emotion on the rest of her face. Kinda creepy, really.
