"identity": "if a photo is uploaded, the face stays the face of that person: keep the shape of the face, the skin tone, the shape of the nose and the mouth, the hair type and colour, the apparent age, and the glasses and beard if there are any. A caricature plays with SCALE, never with identity: the head grows and the body shrinks, but anyone looking still recognises the same person. Do not make them younger, do not slim them down, do not smooth the skin and do not swap the features. With no photo uploaded, invent a 100% fictional person with no resemblance to anyone real",
"subject": "a woman of about 35, brown skin, dark brown tightly curled hair in a high loose bun with curls falling over the forehead and the nape, thick eyebrows, big bright brown eyes with long lashes, flushed cheeks, a wide open smile showing the teeth, small gold hoops in the ears, looking slightly out of frame to the viewer's right",
"caricature_scale": "the head is large and takes up about a fifth of the total height of the body, the skull is wide at the top and the chin narrows, the torso is short and stocky, the hands and the feet are disproportionately big, the legs are short and solid; big rounded shapes, soft corners, little fine detail and a lot of silhouette. Exaggerated proportion, not exaggerated linework: the face stays recognisable",
"wardrobe": "a faded teal denim coverall with the sleeves rolled to the elbow and the legs turned up at the hem, two chest pockets and side pockets; a grey t-shirt underneath showing at the neck; a single orange rubber glove on the hand holding the tool; a red rag hanging from the thigh pocket; worn brown leather lace-up boots with thick soles; dark grease smudges over the arms, the chest and the legs of the coverall; no brand, label or lettering anywhere",
"action": "standing, full body, facing front, with a big brushed-metal adjustable wrench resting on the shoulder, held by the hand in the orange glove, and the other hand closed on the waist; chest out, chin up, the posture of someone proud of their own work",
"scene": "a mechanic's garage at the end of the afternoon, behind the character and entirely out of focus: on the right, a rounded red car raised on a blue lift; on the left, a wall panel hung with wrenches and pliers and a red roll-away tool cabinet; further right, stacked tyres; at the back, the open garage door with the light of the street coming in; a pale concrete floor with sun reflections. All of it in the same 3D caricature style, and no sign, label or readable lettering in any corner",
"composition": "a vertical image in a 3:4 ratio, the character centred and full body, the feet almost touching the bottom edge and the top of the hair close to the top edge, the body filling about two thirds of the width",
"camera": "camera a little below chest height, tilted slightly upwards, full-body distance, shallow depth of field that keeps the character sharp and blurs the whole garage",
"lighting": "warm late afternoon light coming from behind and from the right through the garage door, a golden rim on the hair and the shoulders, soft warm fill on the face, a soft short shadow under the boots, controlled glint on the metal of the wrench",
"color_palette": "the teal of the coverall against the warm orange of the light and of the glove, supported by the grey of the concrete, the red of the car and of the tool cabinet and the brown of the boots",
"style": "3D render with a matte hand-painted finish, saturated colour and cinematic late afternoon light, a friendly and proud mood, no irony and no mockery of the trade",
"materials": "matte, slightly velvety mass on the skin, denim with the texture of worn fabric, brushed metal with a soft reflection on the wrench, matte rubber on the glove, creased leather on the boots, dust and grease as painted patches rather than photographic dirt",
"details": "the job has to be readable from THREE marks at the same time: the work clothes, the tool in the hand and the scene behind. The curls keep loose strands separated against the rim light; the grease patches follow the movement of the fabric; the teeth show whole and aligned in the smile; the adjusting screw of the wrench is visible",
"negative_prompt": "generic doll face, swapped features, a different person from the photo, slimmed face, smoothed plastic skin, face made younger, realistic body with no exaggerated proportion, head at natural size, mockery or an offensive caricature, real branded uniform, text, letters, numbers, readable signage, watermark, logos or real brands, resemblance to a famous person or to a franchise character, deformed hands, extra fingers, melted tool, AI artifacts"

How to use
The caricature trend only works when two things are recognisable at once: you and your job. The exaggeration is one of SCALE — big head, small body, bigger hands and feet — and not of linework: the shape of your face, your skin tone and your hair stay yours. The job shows up in three marks together: the clothes, the tool in the hand and the scene behind. Works in ChatGPT, Gemini and NanoBanana.
1. Upload a front-facing photo, full body or waist up, face well lit.
2. Swap the three marks of your own job: the `wardrobe`, the tool in `action` and the `scene`.
3. Describe yourself in `subject`: age, hair, glasses, beard. A vague field turns into a doll face.
4. If it comes out too exaggerated, shrink the head in `caricature_scale`.
5. Check before posting: if you remove the tool and nobody can guess the job, a mark is missing.
Tip: a job with no tool (teacher, analyst, salesperson) is carried by the object of the day — chalk, an open laptop, a headset — and by the scene behind.
