照片转手绘：柔和童话感二维插画

将整张上传照片转换为干净、色彩丰富的手绘二维卡通插画。保留原始构图、拍摄角度、姿势、面部表情、可辨认的身份特征、发型、服装、配饰以及所有重要的背景元素。

插画风格：
•干净的黑色轮廓线，线条粗细略有变化，呈现手绘感。
•平涂的粉彩色彩，明暗分层极少。
•人物造型简化，比例可爱，表情丰富，姿势自然。
•线条流畅，略有不完美，呈现真实的插画质感。
•将写实纹理简化为干净的形状，同时保留可辨认的细节。
•以相同的卡通风格重现原始环境，包括建筑、树木、喷泉、步道和其他物体。
•使用柔和的粉彩色调，包括浅蓝色天空、低饱和绿意、温暖的肤色和柔和的粉色。
•在保持原场景氛围的同时，添加细微的艺术细节。

保留原图内容：
保持人物数量、位置、身体比例、服装颜色、互动关系和相对大小不变。维持原有背景布局和透视关系。不要添加、删除或重新摆放重要物体。

输出要求：
生成一幅精致、满幅的二维插画，轮廓线统一，色彩平涂，呈现活泼的童话书美学。整张图都必须是插画，不得包含任何写实元素。

避免：3D渲染、照片级写实、过度阴影、水彩纹理、模糊的线条、面部扭曲、多余的手指或肢体、服装改变、姿势改变、背景细节缺失、不需要的文字或水印。

宽高比：与上传照片完全一致。

小提示：一次上传一张照片，并使用同一提示词转换不同照片，以保持卡通风格一致。

Convert the entire uploaded photograph into a clean, colorful, hand-drawn 2D cartoon illustration. Preserve the original composition, camera angle, poses, facial expressions, recognizable identities, hairstyles, clothing, accessories, and all important background elements.

ILLUSTRATION STYLE:
•Clean black outlines with slightly varied, hand-drawn line weight.
•Flat pastel colors with minimal cel shading.
•Simplified characters with cute proportions, expressive faces, and natural poses.
•Smooth, slightly imperfect lines for an authentic illustrated feel.
•Simplify realistic textures into clean shapes while retaining recognizable details.
•Recreate the original environment, including buildings, trees, fountains, pathways, and other objects, in the same cartoon style.
•Use a soft pastel palette with light blue skies, muted greens, warm skin tones, and gentle pinks.
•Add subtle artistic details while maintaining the original scene’s atmosphere.

PRESERVE THE ORIGINAL:
Keep the same number of people, their positions, body proportions, clothing colors, interactions, and relative sizes. Maintain the original background layout and perspective. Do not add, remove, or reposition important objects.

OUTPUT REQUIREMENTS:
A polished, full-frame 2D illustration with consistent outlines, flat colors, and a playful, storybook aesthetic. The entire image must be illustrated, with zero photorealistic elements.

AVOID: 3D rendering, photorealism, excessive shading, watercolor textures, blurry lines, distorted faces, extra fingers or limbs, changed outfits, altered poses, missing background details, and unwanted text or watermarks.

Aspect ratio: Match the uploaded photo exactly.

Pro tip: Upload one photo at a time and use this same prompt to transform different photos into a consistent cartoon style.
