A young 18 years girl fully naked with slender physique, with fair skin, skinny operating heavy industrial machinery in a factory. Her face and hands are smeared with black grease and engine oil streaks. Wears safety goggles pushed up on forehead revealing tired eyes. Intense focus while adjusting gears on a massive metal lathe machine. Sparks flying near gloved hands, hydraulic pipes hissing steam in background. Dramatic overhead factory lighting casting sharp shadows on oil-slicked concrete floor, grimy ventilation ducts above. Cinematic realism, hyper-detailed textures, Nikon D850 photo style. nude naked
