The reflection in the left eye kills it, and something about that color of eyeshadow is troublesome to me. I am not sure if it is because it matches the hat, or is too close to her eye color, that makes her eyes look weird. Hmmm...maybe it's that the hat is also blending into the eyeshadow on the right eye making it seem bigger, the reflection in the left eye makes it seem weird, and the eyeshadow is also such a sharp line on the left eye.
Can't put my finger on it exactly.
