将用户上传的人物照片转化为一张竖版 3:4 的高级极简人像海报。
保留原图中人物的真实身份特征、五官结构、发型、发色、服装、首饰、姿势和整体气质。不要换脸，不要改变人物年龄、性别、种族或核心外貌。可以适度优化皮肤质感、光影、清晰度、服装细节和整体精致度，使画面呈现专业棚拍人像效果。
将原图背景替换为干净的灰白色渐变棚拍背景，背景简洁、柔和、有高级感。人物以半身肖像构图呈现，居中或略微偏右，保留适当留白。光线为柔和均匀的商业摄影灯光，脸部清晰，肤色自然，整体质感细腻、真实、时尚。
画面风格参考高端人像证件海报、时尚杂志封面、Portrait ID 风格、极简主义视觉设计。整体画面干净、克制、专业，具有高级品牌海报感。
在画面左下角加入三行英文文字。用户可以输入自定义文字，如果用户没有输入，则自动生成适合该人物气质的英文文案。用户输入中文时，必须先翻译成自然、简洁、高级的英文后再显示在画面中，画面中不要出现中文。

Transform the user-uploaded portrait photo into a vertical 3:4 high-end minimalist portrait poster.
Preserve the true identity features, facial structure, hairstyle, hair color, clothing, jewelry, posture, and overall temperament of the character in the original image. Do not swap faces, do not change the character's age, gender, race, or core appearance. You can moderately optimize skin texture, light and shadow, clarity, clothing details, and overall refinement to make the image present a professional studio portrait effect.
Replace the original background with a clean gray-white gradient studio background; the background should be simple, soft, and high-end. The character is presented in a half-body portrait composition, centered or slightly to the right, retaining appropriate white space. The lighting is soft and even commercial photography lighting, with a clear face, natural skin tone, and an overall delicate, realistic, and fashionable texture.
The image style references high-end portrait ID posters, fashion magazine covers, Portrait ID style, and minimalist visual design. The overall image is clean, restrained, professional, and has a sense of a high-end brand poster.
Add three lines of English text in the bottom left corner of the image. Users can input custom text; if the user does not input text, automatically generate English copy suitable for the character's temperament. When the user inputs Chinese, it must first be translated into natural, concise, and high-end English before being displayed in the image; Chinese must not appear in the image.
Text typography requirements:
The main title uses a dark blue bold sans-serif font with a larger font size, placed at the very top of the bottom left corner. The subtitle uses a white medium font size, located below the main title. The series text uses white uppercase sans-serif font, located below the subtitle. The three lines of text are overall left-aligned, with simple and clear typography, without obscuring the character's face or affecting the main subject.
Output requirements:
Image ratio is 3:4, vertical poster composition, high-definition, realistic photography texture, high-end minimalist style, commercial studio lighting effect, clean background, fashion portrait poster.
