珠宝腕表商业肖像

生成一张 4:5 竖版高级商业肖像。主体是一位成熟亚洲女性，黑色西装与简洁珠宝腕表，手腕自然靠近面部，突出腕表金属质感与人物气场。深灰棚拍背景，强侧光形成干净阴影，肤色自然，表情冷静自信。画面要像奢侈品珠宝腕表广告，真实摄影质感，85mm 人像镜头，浅景深，人物比例自然，不拉伸不变形。无文字、无 logo、无水印。

Create a 4:5 vertical premium commercial portrait. The subject is a mature Asian woman in a black tailored suit with understated jewelry and a wristwatch, her hand naturally placed near her face to highlight the watch and metal texture. Use a deep gray studio background, clean hard side light, natural skin tones, and a calm confident expression. The image should feel like a luxury jewelry and watch campaign, photorealistic, 85mm portrait lens, shallow depth of field, natural human proportions with no stretching or distortion. No text, logo, or watermark.
