Photorealistic full-body portrait of a tall, slender, ethereal young woman with long, flowing dark hair. She is standing gracefully on a vast desert of pure white sand. Above her, the night sky is a breathtaking cosmic vista, a swirling nebula of deep indigo and violet, filled with countless sparkling stars and the Milky Way galaxy. She wears a weightless, flowing gown made of iridescent, shimmering silk that catches the light like liquid moonlight, in shades of celestial blue and silver. Soft, cool moonlight illuminates her, casting gentle shadows. Cinematic lighting, hyper-detailed, 8K resolution, ultra-realistic.
