Maintain the red knit sweater, white layered lace skirt, sheer tights, and black shoulder bag. Preserve the bouquet with red flowers and white lilies wrapped in warm-toned paper. Keep the architectural stone building facade and decorative metal door details in the background. Enhance realism: natural skin texture, detailed knit fabric, lace transparency accuracy, realistic flower textures, balanced daylight shadows. No text, no logos, no watermark."
