A stunning, cinematic portrait of a woman sitting gracefully on a large coastal rock at a tropical beach during early evening. She has long, flowing black hair, smooth warm-toned skin, and a calm, confident expression. She is wearing a white, flowing summer dress with thin straps and a deep V-neckline, the fabric softly draping around her legs. Her posture is elegant, with one knee bent and her legs crossed as she sits barefoot on the rock. Soft natural light illuminates her face and body, giving a warm, polished, high-end fashion-photography look. Behind her, the beach stretches into the distance with light waves touching the sand. Tall palm trees line the shore, and small beach huts can be seen in the background. A clear sky with a visible full moon adds a serene, dreamy atmosphere. The image has high realism, smooth skin textures, glossy hair details, and crisp focus on the subject, with a softly blurred tropical background. Shot in 8K, ultra-realistic portrait photography style, shallow depth of field, natural colors, editorial beauty aesthetic.
