The Leg Shot - This is a tough area for may photographers and artists. I'll start with this seated image. Notice the leg closest the camera covers the crotch area. Had the leg positioning been swapped you would have been looking into the inside of the far thigh (which isn't a very glamorous pose.) Also, look at the lines of the image. The leg closest the camera draws a line up to her face. Her arm draws a line up to her face. There is a triangle with the apex angle being her face. While a lot of skin is shown in this image, the face is the focal point.
