Create an oil painting of Amaterasu, the Shinto goddess of the sun, in which she is the sun, with skin that glows without casting any shadows upon herself. Her visage exudes pure love and radiant warmth, with a bright, even light that seems to emanate from within. Her features should be illuminated uniformly, showcasing her as a being of pure light. Her hair and attire should also reflect this inner luminosity, with no shadows present. The background should be a subtle glow that accentuates her as the singular source of illumination, in the romantic style of William-Adolphe Bouguereau.
