Photo Background with Doodle Character Replacement

Transform ONLY the people in the reference photo into adorable hand-drawn doodle characters while keeping the original photographic background completely unchanged. Setting & Background: - Retain the exact original photographic environment from the reference photo, including lighting, sky, ground, architecture, furniture, depth, textures, and perspective. - Do not redraw, simplify, or apply doodle/sketch effects to the background or environmental objects. Subject Transformation: - Replace each person with a charming, naive hand-drawn doodle figure while strictly preserving their exact position, scale, pose, orientation (facing forward, profile, or facing away; do not invent hidden faces), and interactions with surroundings. - Keep original clothing color palettes, hairstyles, and key accessories identifiable on the doodle figures. Art Style & Details: - Loose, naive children's crayon or colored pencil sketch style with shaky, imperfect black outlines, uneven scribbled color fills, and white gaps. - Cute exaggerated proportions: oversized round heads, compact bodies, simplified short limbs, tiny dot eyes, and subtle scribbled rosy cheeks when facing front. - Characters must integrate seamlessly into the photographic depth and contact points of the reference photo, holding or touching real-world photographic items naturally.
