对镜自拍：猫耳帽与大衣的极简黑白氛围

A photorealistic profile selfie, minimalist and monochrome: a woman in a dark oversized coat and a black knit hat with cat ears, her hair falling loosely down her back; she holds a black iPhone 17 Pro Max smartphone, taking a picture of herself in an elevator mirror with a matte metal surface in the background. Soft diffused lighting, calm cool color scheme (black, graphite, gray steel), slight film grain, shallow depth of field on the phone and hands, highly detailed fabric and hair textures, 3:2 vertical composition, realistic style, 4K, natural light, soft shadows, moody aesthetic.
