IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while applying the transformation. The likeness must remain recognizable despite the stylization.

TRANSFORMATION DESCRIPTION:
Transform the photo into a funny, exaggerated caricature or cartoon style. The humor should come from playful exaggeration of specific features (like a larger head, expressive eyes, or a quirky pose) rather than mockery. The style should be vibrant, lively, and entertaining, suitable for a fun avatar or meme.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Vibrant digital cartoon or humorous caricature illustration, similar to high-quality animated movie characters or professional editorial cartoons.
- Lighting: Bright, even studio lighting that highlights facial expressions clearly. Avoid heavy shadows that obscure features.
- Color palette: Saturation should be high and colors vibrant. Skin tones must remain natural and match the original photo.
- Background: Keep the background simple and non-distracting. A solid color or a very subtle blurred environment works best to keep focus on the funny portrait.

TECHNICAL QUALITY PARAMETERS:
- high resolution, 4K, detailed
- sharp focus on face
- professional quality
- Aspect ratio: 1:1 (square) or 4:3 (portrait) recommended for social media usage.

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted features that lose likeness, unrealistic proportions that look grotesque, blurry face, loss of facial identity, low resolution, pixelated edges, watermark, text, signature, extra limbs, deformed hands, ugly, tiling, poorly drawn face, mutation, mutated.

USER CUSTOMIZATION:
