红色马克笔背景下的写实人像

Use the uploaded image as the only reference. Keep the person exactly the same, preserving their face, pose, clothing, hairstyle, lighting, colors, and proportions. Remove the original background and recreate the same environment as a {argument name="sketch style" default="loose hand-drawn sketch using only deep crimson red felt-tip marker lines"} on a {argument name="background color" default="pure white background"}. The sketch should be quick, playful, imperfect, and confidently hand-drawn with medium-thick strokes, slight wobble, pressure variation, tiny gaps, and marker bleed—not vector art or technical line work. Keep the person 100% photorealistic with no sketch effect or outline applied to them. Place the subject naturally in front of the illustrated background, ensuring all {argument name="marker color" default="red"} sketch lines remain behind the person. Add a small rounded-corner inset in the bottom-right corner showing the original uploaded photo of the exact same person and scene before the transformation for a clear before-and-after comparison. Ultra-clean editorial style, high resolution, strong contrast between the realistic subject and the bold red sketch, no extra colors, no gradients, and no paper texture.

仅使用上传的图像作为参考。保持人物完全不变，保留其面部、姿势、服装、发型、光影、色彩和比例。移除原始背景，并将相同的环境重新创建为 {argument name="sketch style" default="仅使用深绯红色马克笔线条绘制的随性手绘草图"}，背景设为 {argument name="background color" default="纯白色背景"}。草图应呈现出快速、灵动、不完美且自信的手绘感，线条中等粗细，带有轻微抖动、压力变化、细小间隙和马克笔晕染效果——而非矢量图或技术线条。保持人物 100% 照片级真实，不对其应用任何草图效果或轮廓线。将主体自然地置于插画背景前方，确保所有 {argument name="marker color" default="红色"} 草图线条均位于人物后方。在右下角添加一个圆角小插图，展示转换前原始上传的照片，以便进行清晰的对比。风格简洁利落，高分辨率，写实主体与醒目红色草图之间形成强烈对比，无额外色彩，无渐变，无纸张纹理。
