Subject stands centered, looking directly at camera with a calm, slightly melancholic expression. Snowflakes and frost visibly collecting on clothing and hair.\n\nSubject: ONE adult woman. Soft natural facial features, no beauty filter, realistic skin texture.\n\nWardrobe: dark winter coat ({argument name="coat color" default="black or charcoal"}) with visible snow dusting. A bold red knitted scarf wrapped around the neck (thick wool texture). A bold red fluffy winter hat (faux-fur or plush), matching the scarf. The red accessories are the main color accent in an otherwise muted winter palette.\n\nDetails: wind-blown strands of hair across the face, moist eyelashes, subtle rosy cheeks from cold. Realistic snow particles at multiple depths, cinematic shallow depth of field.\n\nLighting: overcast winter daylight, soft and diffused, no harsh shadows, no HDR. Editorial realism, high detail. NO TEXT."
