Subject stands centered, looking directly at the camera with a calm, slightly melancholic expression. Realistic snowflakes and frost visibly collect on clothing and hair.",
      "subject": "One adult woman with soft natural facial features, unretouched realistic skin texture, and no beauty filters.",
      "wardrobe": "Dark winter coat in [black or charcoal] dusted with real snow; bold red chunky wool knitted scarf around the neck; matching bold red plush faux-fur winter hat serving as the vivid color accent against a muted winter palette.",
      "details": "Wind-blown strands of hair across the face, moist eyelashes, subtle rosy cheeks from the cold. Snow particles drifting at multiple depths with cinematic shallow depth of field.",
      "lighting": "Diffused overcast winter daylight, soft shadows, natural dynamic range, editorial photography realism. No text."
