Korean-style idol fashion portrait at a seaside weather station

Primary request: Create a photorealistic image of a fictional adult Korean female idol in her mid-20s, not resembling any real celebrity, with a poised but private fashion portrait mood.

Scene/backdrop: a small coastal weather station platform, concrete steps, pale instrument boxes, a simple wind vane, thin sea fog, soft clouds, no readable labels.

Subject/clothing/pose: she wears a silver-grey windbreaker over a cream knit top, a pleated charcoal midi skirt over opaque tights, and minimal white sneakers. She sits on the concrete step with one knee raised and one foot lower, holding the string of a small matte white weather balloon just out of frame while her other hand steadies against the step. Hair moves gently in the wind; expression distant, lips relaxed.

Style/medium: Japanese negative film aesthetic, soft natural coastal light, slight overexposed fog highlights, low contrast, muted faded colors, subtle grain, imperfect composition, memory-like realism.

Constraints: adult subject, tasteful non-explicit fashion portrait, no nudity, no minors, no logos, no readable text, no watermark.

Avoid: rooftop, cold bottle, plastic bag, white oversized shirt, shorts, dramatic sci-fi lab look, real celebrity likeness.

Main request: Create a photorealistic image featuring a fictional adult Korean female idol in her 20s, who should not resemble any real-life celebrity, conveying a composed yet intimate fashion portrait mood.

Scene/background: a small coastal weather station platform, concrete steps, pale instrument boxes, a simple wind vane, light sea fog, soft clouds, and no readable labels.

Subject/clothing/pose: she is wearing a silver-grey windbreaker over a cream knit top, a charcoal-grey pleated midi skirt, paired with opaque tights and minimal white sneakers. She is seated on the concrete steps, with one knee raised and one foot lower, holding the string of a matte white weather balloon just outside the frame, while her other hand supports her on the step. Her hair drifts gently in the wind; her expression is distant, with relaxed lips.

Style/medium: Japanese negative film aesthetic, soft natural coastal lighting, slightly overexposed fog highlights, low contrast, soft faded colors, fine grain, imperfect composition, and memory-like realism.

Constraints: adult subject, tasteful non-explicit fashion portrait, no nudity, no minors, no logos, no visible text, no watermark.

Avoid: rooftops, cold bottles, plastic bags, oversized white shirts, shorts, dramatic sci-fi laboratory aesthetics, and resemblance to real celebrities.
