Retrato Nocturno en Playa con Flash

Candid photorealistic night beach portrait of [a young woman] standing on wet sand near the shoreline, framed from mid-thigh up, facing the camera with a relaxed posture and one arm hanging naturally at her side. She has [long straight dark brown hair parted near the center], [smooth light-to-medium skin], and wears [a fitted strapless bodycon dress with a soft vintage floral print in muted cream, pale yellow, sage green, and dusty blue], accessorized with [a delicate gold necklace with a small round pendant] and subtle rings. Direct on-camera flash lighting, casting crisp highlights on the skin and sharp contrast against a pitch-black background with a visible band of foamy ocean waves behind her. Smartphone snapshot aesthetic, authentic flash harshness, realistic skin texture, centered composition, casual social media nightlife vibe.
