During Akhenaten's reign, royal portraiture changed. Sculptures of Akhenaten are different from those of earlier pharaohs. Akhenaten is shown in an androgynous (less manly) and stylized manner, with large thighs, a slim torso, drooping belly, full lips, and a long neck and nose. Some believe that the break with convention was due to "the presence at Amarna of new people or groups of artists whose background and training were different from those of the Karnak sculptors".
