Klaus_v3 - LoRA Training Protocol

Physical Description (The "Long" Prompt):

A lean, wiry German man in his late forties to early fifties with an unmistakably distinctive presence. His hair is extremely short—nearly shaved, a fine dark brown stubble with scattered grey, cropped so close it is almost skin. His eyes are pale blue/grey-blue, direct and slightly deep-set. His face is very long and narrow with gaunt hollow cheeks, prominent orbital bones, sunken temples, and a sharp jawline—a face of pronounced angles and no softness. His nose is long and narrow with a slight hook. His lips are thin and naturally downturned, giving his default expression a dry, unimpressed quality. His ears are noticeably prominent and slightly protruding. His skin is pale fair with visible age spots, moles, and skin irregularities scattered across his chest, shoulders, and arms—authentic and lived-in. He wears simple round black-framed glasses—classic small round acetate frames, no embellishment. His build is authentically lean and wiry: very low body fat, narrow shoulders, flat chest, long thin limbs with visible sinewy definition but zero bulk. This is a thin working man, not an athlete and not a medical case—functional, capable, and real.

Character Anchor (The Core Identity):

German, Central European origin, round black-framed glasses (KEY ANCHOR), nearly shaved ultra-short dark/grey hair, pale blue-grey eyes, very long narrow gaunt face, hollow cheeks, prominent ears, long hooked nose, thin downturned lips, pale fair skin with age spots/moles, very lean wiry build, late 40s/early 50s male.

Body Training Note:

The reference images show exactly the correct body calibration: authentically lean, wiry, and thin—but NOT emaciated, NOT skeletal, NOT unhealthy. Models strongly bias toward extreme thinness when given these features. The target is "thin working man, wiry frame" not "starvation physique." Keywords: thin wiry build, lean working man, sinewy but functional, narrow but upright, not emaciated, not skeletal.

Glasses Variant Note:

Klaus wears round black acetate glasses consistently across all reference images. These are a core character anchor and should appear in most training contexts. Keyword: round black glasses, small round frames, black rim glasses. Without glasses, the face reads very differently—train with-glasses as the default.

Negative Prompt:

Muscular build, athletic build, broad shoulders, thick arms, overweight, heavy, healthy-looking or full face, plump cheeks, smooth unaged skin, dark eyes, brown eyes, warm expression, smile, beard, stubble, long hair, curly hair, no glasses, rimless glasses, metal frames, earrings, jewelry.
