Retrato en la Playa con Flash al Atardecer

Upper body portrait of [a person] standing on a beach at twilight, shot from behind as they turn over their shoulder toward the camera, cropped from above the waist. The subject has sun-kissed, glowing skin with a subtle shimmer, and windswept surfer-style hair. Wearing [a light yellow, loose, half-open linen shirt with rolled-up sleeves] and [a delicate gold seashell necklace]. Direct on-camera flash illumination creates a striking contrast against the dark background. In the backdrop, the sun has 98% set, leaving a deep purple-red twilight sky over the darkening ocean. Candid flash photography style, high aesthetic realism.
