Many issues. Her right breast (that is, our right) is being squeezed by her arm and covered by the cloth, despite her arm reaching behind her torso. The ropes should be squeezing her breasts. Her cleavage reaches too far up her chest (they're either too high up or the torso isn't long enough, can't tell). The base of her neck is poorly defined, and her neck in general appears too squat. The angle of her arms suggests they are bent beyond the range of her shoulders. Her rib lines are much too sharp, and her abdomen line (the heck do you call that?) isn't straight. The design of her panties is a bit confusing (too many layers?). Part of her face appears concave, and it's asymmetrical. Something is up with the positioning of her face vs the size of her head but I can't quite figure it out.
