Ritratto Notturno a Bordo Piscina con Sguardo Indietro

High-definition photorealistic night portrait of an adult woman sitting by a [night pool at a tropical resort], captured from behind as she looks back over her left shoulder toward the camera. She has a slender oval face, light brown almond-shaped eyes, delicate eyeliner, faint blush, and soft coral-pink lips with a serene expression. Her long light brown wavy hair falls past her shoulders with translucent thin bangs and loose strands flowing down her back. She is wearing [an elegant gray one-piece swimsuit with a modest neckline]. She sits sideways on the stone pool edge with bent knees, leaning on both hands beside her. Setting & Lighting: A luminous deep blue pool with subtle underwater lighting and warm ambient reflections on water ripples. In the background, blurred lounge chairs, parasols, a wooden deck, a pergola, and tall tropical palm trees under a dark night sky. Direct soft warm flash lights the subject's face, hair, and shoulders, while the blue pool casts a gentle ambient rim light along her silhouette. Composition: Vertical 3:4 framing, medium close-up taken from a rear-diagonal angle slightly above shoulder height, focusing sharply on her face and hair with shallow depth of field.
