Petra — a young woman in her mid twenties, London, with long thick wavy hair that is deep auburn at the roots and melts through the lengths into a lighter copper ginger toward the ends, clear blue-grey eyes with both irises exactly the same colour, fair warm-toned skin carrying a light scatter of real freckles across the bridge of her nose and both cheeks, an oval face with a softly tapered jawline and a gently rounded chin, a straight nose with a slightly upturned tip, full lips with a pronounced cupid's bow, a medium natural bust, and a slim build. An original synthetic character — she is an AI model, not a real person.
CHARACTER APPEARANCE
— Hair: long, thick and softly wavy, never straightened flat. The colour is the ombre — a deep auburn red at the scalp and roots, melting gradually through the mid-lengths into a lighter coppery ginger at the ends. That graduation is her signature and it is part of the identity, not a styling choice.
— Eyes: clear blue-grey — slate blue with a grey cast, not navy. Both irises are identical in colour; if one comes out warmer or brighter than the other, the sampler is at fault, not the LoRA.
— Skin: fair and warm-toned, with real texture — fine grain, visible pores on the nose and cheeks, and a light natural scatter of freckles across the nose and both cheekbones. The freckles are hers, so never put freckles in a negative prompt.
— Face: an oval frame with a softly tapered jawline and a gently rounded chin. Her bone structure is soft and feminine, not angular and not square.
— Brows: natural and softly defined, a shade darker than the lengths.
— Nose: straight, a narrow bridge and a slightly upturned tip — bridge width and tip angle are two of her three identity-critical features.
— Lips: full, with a pronounced, clearly defined cupid's bow — the third.
— Bust and build: a medium natural bust, slim waist, soft rounded hips, long limbs. Naturally proportioned, never exaggerated.
Her look is warm, autumnal and unposed: freckles, copper hair, an overcast window, no effort.
WHO SHE IS: a ginger lifestyle creator who shoots her own content from her flat — cosy knitwear, rainy afternoons, kitchen light, mirror selfies, pumpkin season. Domestic and British rather than gym or studio, and completely comfortable in front of a lens.
HOW TO USE — ONE FILE, ONE LOADER:
UNETLoader -> LoraLoaderModelOnly (petra_face @ 1.0) -> KSampler
The file carries UNet attention keys only, so LoraLoaderModelOnly is enough — there is nothing to wire onto the CLIP path.
Trigger: petra_face — put it at the head of the positive prompt.
LORA WEIGHT
A good starting range to test is: 0.8 – 1.2
Suggested starting point: 1.0
Measured on this base: 1.0 gives her actual face. Below about 0.45 she relaxes toward a generic redhead and the ombre flattens to one flat copper — that is not a lighter version of her, it is a different woman. If her features feel too strong, move in 0.1 steps and check the nose bridge, the lip bow and the hair graduation, not just the overall impression. This preview gallery was rendered at 1.0, the same weight recommended here.
PROMPTING PETRA — THE IMPORTANT STUFF
Minimal identity string:
petra_face, young woman, long wavy copper-auburn hair with ginger ends, blue-grey eyes, fair freckled skin, oval face, full lips with a defined cupid's bow, slim build, medium bust.
For full-body, nude or topless frames, extend with:
slim build, medium natural bust, narrow waist, soft rounded hips, long limbs, balanced natural feminine proportions, freckles across the nose and cheeks
She works well across:
— cosy domestic interiors — sofa, bed, kitchen counter, bathroom vanity
— knitwear, wool jumpers, heavy cotton, autumn layers
— mirror selfies and phone-camera close portraits
— lingerie, bikini and swimwear in overcast daylight
— rain-streaked windows, pumpkin season, tea-and-blanket scenes
HAIR
Her hair is the ombre, and it is the first thing that drifts. Describe it as a physical fact — "deep auburn at the roots at her scalp melting softly through the lengths into a lighter coppery ginger toward the ends" — and keep the straight-hair family in the negative: straight hair, sleekly combed hair, a tight bun, a ponytail, a braid, tight ringlets. She can wear it up or half-up and still read as her, but the graduation survives better loose.
Do NOT write "no roots", "roots covered" or "even colour" — a negation in the positive summons exactly the hard dye line you are trying to avoid. Assert the root colour instead, and let the negative carry only the wrong families: black, brunette, blonde, platinum, ash.
SHE LOOKS BEST WHEN PROMPTS EMPHASIZE
— realistic natural skin texture, film grain, an honest sensor
— her freckles across the nose and both cheeks
— her full lips and the defined cupid's bow
— soft overcast window light, north light, a wet grey afternoon
— the auburn-to-ginger graduation in her hair, slim build with a medium natural bust
BASE MODEL / BODY-BIAS BLOCK
The base may bias proportions upward and the bust larger than hers. Reinforce with:
medium natural bust, slim build, narrow waist, soft rounded hips, long limbs, balanced natural proportions, realistic body shape
Avoid over-sharpened features, artificial smoothing and heavy glamour makeup — the nose bridge width, the lip thickness, the cupid's bow and the hair graduation are the identity-critical features, and they should stay consistent across every generation.
NEGATIVE PROMPT TIPS
— NEVER ban a garment she is wearing — a bare "bikini" in the negative deletes the bikini off her body. Ban only what she is NOT wearing, and state the state you want in the positive.
— Never put freckles in the negative. They are hers.
— Printable-text family: text, logo, lettering, signature, letters, words, numbers, watermark.
— Mirror family: mirror, reflection, mirrored wall, reflected figure — drop it for an actual mirror selfie.
— Colour drift family: blonde, platinum blonde, ash blonde, jet black hair, brunette hair, hard root line, dyed band, bleached roots.
— Eye family: heterochromia, two different eye colours, mismatched eyes, odd eyes, brown eyes, hazel eyes, green eyes, one iris pale and desaturated.
— Plastic family: plastic skin, waxy skin, airbrushed skin, smooth doll skin, mannequin, implants, fake breasts, huge breasts — and keep her build words in the positive.
— Anti-plural family: two women, second woman, duplicate, second person, extra limbs, extra hands, extra fingers, crowd, group.
