Both Models also have a very intense connection with the camera and are speaking with their eyes.
Both models are using different poses as the model on the left exposes the neck to accent the sweater and compliment the tone of the wardrobe with the skin tone the other uses the arm, the hair to accent the white garment. Usually the neck is shown to give the longer symmetry but the alternating skin tone of the model on the right creates a symmetry of color.
