Character Consistency Prompt: Dual-Scale Person & Mini-Me

This character consistency prompt is a masterpiece of “Conceptual Realism.” It’s not just an image; it’s a narrative technique. In the AI community, creating two versions of the same person—one realistic and one caricatured—in a single frame while maintaining perfect identity and clothing consistency is a high-level skill.

Most AI generators choke when you ask for the same person twice in one frame. You usually end up with two people who look vaguely like cousins, but never the same person. This prompt is a workaround for that “Identity Drift.” By framing the second figure as a “miniature caricature,” you give the model permission to distort the proportions (big head, tiny body) while you demand it keeps the bone structure and skin tone identical to the life-size version. The inclusion of the SpongeBob shirt is the ultimate stress test—if the AI can’t sync the graphic on both shirts, the seed is bad. It’s a brutal test of a model’s precision, but when it hits, it’s a perfect concept piece.

Prompt For Character Consistency

### Visual Concept & Composition
A hyper-realistic 8K cinematic studio scene, shot with a 35mm lens and shallow depth of field. A life-size woman is on the right side of the frame, shown from the chest up, holding a much smaller, stylized, cartoonish version of herself. Both figures represent exactly the same person from the attached reference photo.

### Identity Preservation
Faithfully preserve all facial features, bone structure, face shape, and natural proportions from the reference photo. No idealization or artificial smoothing. Both the life-size and miniature figures must share the same long brown hair, skin tone, and overall visual identity.

### The Life-Size Subject
- EXPRESSION: Looking downward at the miniature with a confused and amused expression; softly furrowed eyebrows and a subtly open mouth.
- ATTIRE: An oversized gray t-shirt with a colorful SpongeBob print (reproduced with absolute fidelity).
- DETAIL: Realistic fabric behavior, visible micro-texture, and highly detailed photorealistic hands holding the miniature.

### The Miniature Subject (The Mini-Me)
- STYLE: Same woman on a reduced scale but with cartoonish proportions (oversized head, tiny body).
- EXPRESSION: Exaggerated terror or rage; mouth wide open screaming, bulging eyes.
- ATTIRE: Exact same oversized gray SpongeBob t-shirt, perfectly identical in color and print.

### Lighting & Environment
- LIGHTING: Dramatic cinematic soft diffused key light from front-left; subtle rim light on the right to define the silhouette.
- BACKGROUND: Dark, neutral, and lightly textured to keep focus on the subjects.

### Technical Quality
Ultra-high micro-detail in skin pores, hair strands, fabric fibers, and materials. Strong contrast between extreme photorealism and controlled caricature.

How to Hack This

The Clothing Glue: The SpongeBob shirt is the “glue” that holds the shot together. If you want to change the outfit, pick something with a complex logo. This forces the AI to focus on detail replication rather than just “guessing” a color.
Fixing the Face: If the miniature doesn’t look enough like the reference, add extreme facial likeness match to the Miniature Subject section.
Control the Chaos: If the mini-me looks too “human” and not “cartoony” enough, amplify the oversized head and caricatured proportions keywords.
The Background: If a dark studio is too boring, swap it for a cluttered workshop to make it look like a mad scientist created the miniature.
