Ultra-Realistic Urban Winter Portrait

{
  "prompt": "A confident young woman with long, straight vibrant {argument name="hair color" default="red"} hair stands casually in a snowy urban underpass, leaning against a brick wall covered in colorful graffiti with bold orange, teal, and black designs. She has fair skin dusted with natural freckles, striking blue eyes enhanced by subtle makeup, long lashes, and glossy nude-pink lips in a calm, self-assured expression. She wears a shiny pink cropped puffer jacket with a high collar and quilted texture, zipped low to reveal her toned midriff, paired with high-waisted white seamless leggings that hug her curvaceous hips and strong thighs. Her pose is relaxed yet bold, one hand tucked into her jacket pocket, the other resting by her side, as snow dusts the ground and edges of the tunnel. Cold winter daylight filters in, casting soft natural highlights on her hair, skin, and the glossy jacket fabric, creating a cool, urban winter vibe. Ultra-realistic skin texture and freckle details, high-detail puffer jacket sheen and graffiti patterns, highly detailed hair strands catching the light, snow accumulation, and gritty city tunnel atmosphere."
