She sports an asymmetric bob hairstyle, her hair cut to ear-length. She has an impressively straight nose contour, with the base of her nose being equally straight. The image is a splendid display of macrophotography, with a shallow depth of field adding an extra layer of interest to it. The textures are incredibly detailed, adding much to the overall realism of the image.",
