Transform my uploaded photo into a winter scene, preserving my face, age, gender, clothing, accessories, and pose. Environment: winter street, fluffy snowdrifts at the edges and in the background, cold atmosphere, light mist/steam. Weather: falling large soft snow (multiple layers - foreground and background), visible snowflakes of different sizes, realistic depth of field. Interaction: natural snow on shoulders, hair/headwear, and clothing folds; light frost on stray hairs; snowflake highlights on the face without obscuring expressions; light wetting on the edges of the fabric. If eyebrows/eyelashes are visible, add a thin dust of frost. Light: cold daylight (bluish-neutral) with soft shadows; if an evening photo, add cold street lights and a light warm rim light. Background: clean, no readable signs/text; snow-covered trees/benches/cars, footprints in the snow according to the perspective. Physics: snow lies top-down following gravity and wind direction; thin edges of snowdrifts are soft, not 'plastic'. Color correction: cold winter palette, soft contrast, light 'cold haze', without aggressive blue. Maintain the sharpness of the eyes/face, do not change the expression, makeup, or hairstyle.
