Head Swell

[Subject] Use the person from @person as the main subject, whoever they are, preserving their exact face, facial features, skin tone, hairstyle, clothing, accessories and body proportions so they are instantly recognizable. The only change is the head: it is enlarged into a big-head caricature style, about 2 to 3 times larger than normal relative to the body, while the face stays photorealistic and identical to the reference. [Action] The subject keeps exactly the same pose, gesture, expression and body position as in @person. The body, arms, hands, legs and clothing remain at their original size and posture, and only the head is scaled up, sitting naturally on the neck and shoulders. [Location/Context] Keep the original background, environment, props and surrounding objects from @person exactly as they are, unchanged. [Composition] Keep the original framing, camera angle, crop and aspect ratio of @person. The enlarged head stays fully inside the frame with nothing cut off, and the neck and shoulders connect smoothly to the oversized head with natural perspective and proportions. [Style] Photorealistic big-head effect with seamless blending between the enlarged head and the body. Maintain the original lighting, color grading, skin texture, sharpness and image quality of @person. Hair, ears, jawline and neck are scaled consistently with the head, with clean edges and no visible editing artifacts. [Negative] Changed face or likeness of @person, altered clothing, altered background, changed pose, enlarged body, enlarged hands, distorted facial features, mismatched head and neck connection, blurry or stretched face, extra limbs, cartoon or illustration style, new objects, text, watermark.
