桥工地上指着钢梁的黑辫女工程师

Subject: a fictional adult Native American engineer, a woman in her thirties with a thick black braid, in a safety vest over a plain shirt and a hard hat. She stands on a bridge construction site, a rolled set of plain blueprints in one hand and the other pointing at a steel girder, with a river and a half-built bridge arch behind her. She has natural, realistic features and a dignified, confident expression, and wears everyday modern clothes: no feathers, headdress, face paint, regalia, fringe or costume, no text, logos or name badges, and no stereotyped props. Frame: square 1:1, centred composition with breathing room on all sides. Style: clean animation-style character drawing. Slender dark contours, smooth flat colour shapes and a few precise cel-shaded planes; warm, clear middle values with dark, even linework; simple readable gestures; adult faces with large round eyes, fine arched brows, tiny noses and restrained expressive mouths; soft even light that leaves only light shadows on cheek and neck. Light and colour: soft even daylight. Flat shapes in safety orange, steel blue and warm tan, with precise cel-shaded planes on the vest and the girder, a pale sky and a river behind. Palette: safety orange, steel blue, warm tan, sky. Clear, competent, clean.
