Actually, the shot was composed with a flash from above (note the boob shadow). If a grid was used, the upper body would be over exposed, and the arms would be exposed by the auxilary lighting, giving you different skintones.

I agree with Charlie, this image is very poor. you can tell that her arms, boobs, shouldres and the colour is fake. put the real picture of her up there and you might get some good remarks back.

Tired of this look, also she looks so head stripped! Arms and body don't match the head. They are completely different colors too. Poor.
