9:16 vertical format, 4K resolution, documentary snapshot style, mimicking the effect of casual everyday selfies and impromptu grabs, using the iPhone 17 Pro main camera shooting parameters, 24mm focal length, powered by computational photography, deep depth of field, sharp and crisp imaging. The main subject is a young woman with a porcelain-doll-like delicate face, fair and flawless skin, large icy-blue round eyes, long and defined eyelashes, a small and refined nose, full lips, and a composed expression; platinum-blond hair is braided into two neat thin plaits, her fingernails feature striking sapphire-blue polish, and she wears a light blue fitted Korean-style short jersey for the World Cup, with smooth natural body curves, soft and graceful contours, relaxed and well-proportioned physique, naturally defined waistline, fluid shoulder-waist-hip lines, innate soft body curvature, and a balanced, elegant silhouette. Captured from a high-angle selfie perspective, with one hand raised to shield against harsh light, she looks up toward the camera with a flat expression, eyes wide open, gaze vacant and doll-like. The setting is the Korea match at the daytime USA-Mexico-Canada World Cup stadium, using natural light complemented by sand reflection as fill light, with top lighting combined with global diffuse fill for illumination, delivering soft and diffused light quality, overall bright and well-exposed, standard daylight color temperature of 5500K; strong reflective质感, presenting her skin with a smooth, flawless porcelain texture, with maximum detail rendering.
