In this image, while you roll your mouse over the photo and back off again, look at: the thinning of her arm, color of the eyes, adding shape to her back, smoothing of the veins in her left hand, matching of the hair color where her roots are showing & enlarging of her breasts. In normal conditions & would also fix the skin, but in Kayla's case she has wonderful skin so I did not need to do this. I  look for models, like Kayla, that have good  body & facial "Structure" because if that is there I can fix the rest.
