Prompt:"A photorealistic portrait of the woman, strictly preserving her exact facial identity, eye shape, eye color, and natural brown hair characteristics. Her genuine, wide smile is identical to the expression, perfectly adapted to a new pose. She is wearing the same black turtleneck sweater. The background is a seamless, cozy, snowy evening scene with the Christmas tree and warm string lights, maintaining the exact bokeh effect, depth of field, and gentle snowfall. The composition is a perfect 1:1 square aspect ratio, focused tightly on her expression. The lighting is soft and ambient, highlighting her features."
