原景保留的人物涂鸦替换

仅将上传照片中的人物变成可爱的手绘涂鸦角色，同时保持原始照片背景不变。

核心规则：
背景＝原始写实照片。
人物＝可爱的手绘涂鸦角色。

保留背景：
尽可能保持原照片中的天空、景观、建筑、水面、家具、地面、植物、栏杆、物体、光线、色彩、透视、拍摄角度、构图和纹理。

不要重绘、简化或插画化背景及环境中的物体，也不要对它们施加涂鸦、蜡笔或铅笔效果。

仅变换人物：
将每个人替换为迷人、天真的涂鸦版本，同时保留：
- 人物的确切数量
- 原有位置和相对比例
- 正面、背面、侧面或四分之三侧面的朝向
- 头部和身体的方向
- 姿势和手势
- 手臂和腿的位置
- 与其他人或物体的互动
- 发型、服装颜色和主要配饰

重要：
如果人物背对镜头，保持背对。
如果人物侧身，保持侧身。
如果人物面向前方，保持面向前方。
绝不要将人物转向观众，也不要凭空画出原本看不见的脸。

可爱涂鸦风格：
自由地将真实人体结构重新诠释为可爱、不完美的角色：
- 大大的圆脑袋
- 小巧紧凑的身体
- 简化的短胳膊和短腿
- 小手小脚
- 可爱而笨拙的比例
- 随意涂画的头发
- 可见时画出小点眼睛和简单的五官
- 适当时用涂画表现红润的脸颊

保持原有姿势可辨认，但为了增强可爱感，可将其简化并略加夸张。

绘画风格：
松散、天真的手绘涂鸦，像儿童随手画的速写。
使用细而颤抖的黑色轮廓线、不完美的形状、相互重叠的草图线条、随意涂画的彩铅或蜡笔填色、不均匀的上色、留白和略显凌乱的边缘。

角色应看起来是刻意粗略画成的，但极其可爱。

物体：
人物周围的物体、家具、景物和用品应尽可能保持照片质感。涂鸦角色可以自然地触碰或拿着真实的照片中的物体。

融合：
保持正确的比例、与地面的接触、空间纵深和遮挡关系，让涂鸦角色自然地处于原人物所在的位置。

最终效果：
画面应给人一种感觉：真实人物从原照片中被移除，取而代之的是他们各自可爱的小手绘涂鸦版本，而现实世界的背景保持原样。

优先考虑：
1. 原始照片背景
2. 人物位置和比例
3. 精确的身体朝向
4. 姿势和手势
5. 可爱夸张的涂鸦角色设计

避免整张图片插画化、背景涂鸦、真实人体结构、动画风格、漫画风格、3D 卡通、精致的数字艺术、矢量线条、改变姿势、改变朝向、增加人物或凭空创造面孔。

Transform ONLY the people in the uploaded photo into adorable hand-drawn doodle characters while keeping the original photographic background unchanged.

CORE RULE:
Background = original realistic photo.
People = cute hand-drawn doodle characters.

PRESERVE THE BACKGROUND:
Keep the original sky, landscape, buildings, water, furniture, ground, plants, railings, objects, lighting, colors, perspective, camera angle, framing, and textures as close to the original photo as possible.

Do NOT redraw, simplify, illustrate, or apply doodle/crayon/pencil effects to the background or environmental objects.

TRANSFORM ONLY PEOPLE:
Replace each person with a charming, naive doodle version while preserving:
- exact number of people
- original position and relative scale
- front/back/side/three-quarter orientation
- head and body direction
- pose and gesture
- arm and leg positions
- interactions with people or objects
- hairstyle, clothing colors, and major accessories

IMPORTANT:
If someone faces away, keep them back-facing.
If sideways, keep them sideways.
If facing forward, keep them forward.
Never rotate a person toward the viewer or invent a face that is not visible.

CUTE DOODLE STYLE:
Freely reinterpret realistic anatomy into an adorable, imperfect character:
- oversized round head
- tiny compact body
- short simplified arms and legs
- tiny hands and feet
- cute awkward proportions
- loose scribbled hair
- tiny dot eyes and simple facial features when visible
- rosy scribbled cheeks when appropriate

Keep the original pose recognizable, but simplify and slightly exaggerate it for cuteness.

DRAWING STYLE:
Loose naive hand-drawn doodle, like a quick children's sketch.
Use thin shaky black outlines, imperfect shapes, overlapping sketch lines, scribbled colored-pencil or crayon fills, uneven coloring, white gaps, and slightly messy edges.

The character should look intentionally roughly drawn but extremely cute.

OBJECTS:
Objects, furniture, scenery, and items around the people should remain photographic whenever possible. A doodle character may naturally touch or hold a real photographic object.

INTEGRATION:
Keep correct scale, ground contact, depth, and occlusion so the doodle characters naturally occupy the same locations as the original people.

FINAL LOOK:
It should feel like the real people were removed from the original photograph and replaced with adorable little hand-drawn doodle versions of themselves, while the real-world background remained untouched.

Prioritize:
1. Original photographic background
2. Person position and scale
3. Exact body orientation
4. Pose and gesture
5. Cute exaggerated doodle character design

Avoid full-image illustration, background doodling, realistic anatomy, anime, manga, 3D cartoon, polished digital art, vector lines, changed poses, changed orientation, added people, or invented faces.
