GPT Image提示词：

A frontal portrait of an adult woman with a calm, direct gaze, framed by an ornate silver mechanical crown that blends fine clockwork with branching fractal patterns. Her face is natural and expressive, with subtle metallic inlays tracing the temples and cheekbones like elegant ceremonial ornament. Layered steel filigree rises above her head, punctuated by small glass lenses and delicate engraved details. She wears a high-collared sculptural garment in graphite and brushed silver, with no exposed skin beyond the face and hands. A dark, softly lit studio background keeps attention on the symmetrical composition and intricate silhouette. Cool white key light reveals the polished metal while a restrained warm reflection adds depth to the eyes. Vertical editorial portrait, centered framing, precise facial detail, refined science-fiction craftsmanship, high contrast without harshness, crisp focus, premium digital illustration.
