Miniature Cartoon Doppelganger Portrait

Title: Please generate a creative studio portrait based on a user-uploaded photo, strictly preserving the real facial features, face shape, hairstyle, hair color, skin tone, expression, and clothing characteristics of the reference person to ensure a high degree of recognizability. The image should be a close-up or half-body vertical composition, with the subject centered. The subject should be smiling naturally, looking at a miniature cartoon doppelganger on their fingertip. The doppelganger is a scaled-down version of the reference person, using a sophisticated 3D cartoon character style, with cute, exaggerated proportions, large eyes, a friendly and playful expression, and maintaining the same hairstyle, hair color, facial features, and clothing characteristics as the real person. The overall style blends hyper-realistic portrait photography with high-quality 3D animated character rendering. Both real faces and miniature character faces are clear and sharp. The background is a pure studio background in dark or neutral colors, with shallow depth of field blur, soft cinematic lighting, natural highlights, and the picture is warm, dreamy, modern, and creative. It has high resolution, ultra-clear image, 85mm lens feel, and 2:3 vertical composition.
