Portrait Steampunk avec Coiffe Mécanique

A meticulously detailed steampunk portrait of a [young woman] shown from the chest up, centered in a vertical composition. She has pale porcelain skin with subtle freckles, striking turquoise-blue eyes, and soft natural makeup. Her hair is a voluminous [pastel pink] updo, loosely gathered into an intricate messy bun with wispy strands escaping around her face. A delicate metallic heart-shaped filigree ornament decorates her cheek. She wears an elaborate brass and bronze mechanical headpiece fusing Victorian aesthetics with industrial engineering, featuring polished gears, rivets, miniature lenses, pressure valves, copper tubing, metallic spikes, and a large circular glowing optical device above her forehead emitting a cool cyan light. Her attire is a richly textured burgundy leather jacket with a dramatic raised collar, visible stitching, metal studs, buckles, straps, and articulated brass steampunk machinery seamlessly integrated into the shoulder. The background softly blurs into the interior of an advanced retro-futuristic airship or industrial laboratory with circular metallic structures. Cinematic volumetric lighting combines cool teal ambient illumination with warm copper highlights, emphasizing reflective metallic surfaces and textures with a shallow depth of field.
