Ultra-realistic fantasy scene of a beautiful young woman sitting gracefully on a stone, under a starry night sky with the Milky Way and shooting stars. She is wearing a shimmering, ethereal gown that reveals her shoulders and midriff, with delicate, flowing fabric that glows softly in the moonlight. The background features distant mountains, a serene landscape, and a magical atmosphere enhanced by the celestial elements in the sky. The lighting emphasizes her elegant pose and the dreamlike quality of the scene, with soft shadows and a gentle glow around her.
