I'm going to agree with Neko on his point re the model's right leg. Given the (gorgeous) way the thigh develops once above the knee, the right leg does not begin this thickening at all.
Nonetheless, the lighting gradient from the face as it moves down the body is very good, and I love the way you used the light to define the material of the stockings. Perhaps the model's right side of her face could be shadowed a bit by the nose? Would the ligaments and tendons of the left hand be that defined at that angle? I'm not sure.
One point on the arm stocking/gloves. Notice how on the right arm, the material seems to grip the musculature of the model's arm. Then look at the left arm. You'll see a gap between the fabric and the arm. I think the material would more than likely grab the the bicep and tricep as well.
Regardless, EXCELLENT work. Top marks for the hair and stretching of the skin on the buttock area.
