Korean Idol Coastal Fog Portrait

Main request: Create a photo-realistic image featuring a fictional adult Korean female idol in her twenties, not resembling any real-life celebrity, presenting a calm yet intimate atmosphere of fashionable portraits. 

Scene/Background: Small coastal weather station platform, concrete steps, light-colored instrument cabinet, a simple weather vane, thin sea fog, soft clouds, no readable labels. 

Subject/Outfit/Pose: She wears a silver-gray windbreaker with a cream-colored knit top underneath, a charcoal gray pleated midi skirt, opaque tights, and minimalist white sneakers. She sits on concrete steps, one knee raised, one foot lower, holding a string of matte white weather balloons just outside the frame, and the other hand supporting herself on the steps. Her hair gently flutters in the wind; Her expression is distant, lips relaxed. 

Style/Media: Japanese negative film aesthetics, soft natural coastal lighting, slightly overexposed fog highlights, low contrast, soft faded colors, delicate graininess, imperfect composition, and a memory-like realism. 

Requirements: adult subject, elegant non-pornographic fashion portrait, no nudity, no minors, no logos, no visible text, no watermark. 

Avoid roofs, cold bottles, plastic bags, oversized white shirts, shorts, dramatic sci-fi lab looks, and real-life celebrity looks.
