Mmmm, skin colour doesn't quite look right. If you load the image into photoshop (or similar), then blur a few times - then use the dropper to find out what her skin color is. Then compare with a reference image. There seems to be a fairly common band of values that represents realistic skin color - somewhere in the RGB=200,140,115 mark (well those proportains anyway). Your skin above has similar amounts of green and blue (so there is too much blue) - and probably not enough red. Just upping the fake sss on the shader might help in the above case with the red, but you probably need to play with the Diffuse_Color in the mat room to reduce the blue.
