### Full prompt
```text
Using the reference photo, transform only the main subject into a charming, hand-drawn children's book caricature with an oversized head, leaving the original photographic background completely intact and photorealistic.

- Subject & Proportions: Dramatically exaggerate the subject's head to roughly 45–60% of their visual height, paired with a tiny, simplified body, short limbs, and small hands and feet. Faithfully preserve the subject's recognizable identity, specific head silhouette, hairstyle, facial hair, skin tone, facial expression, clothing, and accessories. Avoid generic circular heads.
- Style & Technique: Loose, expressive hand-drawn ink and colored pencil illustration. Organic thin-to-medium black ink outlines, visible colored-pencil strokes, rough hatching, uneven fills, imperfect edges, and subtle paper texture. Simple dot or oval eyes, tiny simplified nose, and a gentle curved smile.
- Composition & Lighting: Preserve the exact camera angle, framing, perspective, and original photorealistic environment (furniture, landscape, architecture, lighting). Seamlessly composite the illustrated character into the real scene with matching perspective, lighting direction, and soft grounding contact shadows.
- Constraints: Do not cartoonize the background. Avoid 3D CGI, smooth digital airbrushing, vector art, anime style, or realistic human proportions for the subject.
