Biomechanical Alien Woman Portrait with Brass Halo

Create an ultra-detailed, photorealistic dark sci-fi portrait in a vertical 9:16 composition, featuring a mysterious extraterrestrial female humanoid with an elongated, sculptural head, pale porcelain-white skin, subtle icy-blue and gray undertones, delicate weathered textures, faint marbling, and intricate biomechanical facial modifications. Her face is narrow and symmetrical, with sharply defined cheekbones, deep-set dark eyes partially concealed beneath heavy, shadowed brow ridges, thin ornamental markings, small embedded metallic studs, and delicate circular crimson implants arranged precisely across her forehead and temples. A small polished silver septum ring adorns her nose, while deep burgundy-red lipstick creates a striking contrast against her pallid complexion, her expression calm, severe, and otherworldly. Surrounding her head is an enormous, elaborate biomechanical headdress constructed from concentric arches of aged gold, polished brass, and dark bronze, forming a symmetrical halo of interlocking metallic ribs, layered tubular filaments, intricate engraved channels, tiny mechanical fasteners, and elegant sweeping curves that extend upward and outward like an alien ceremonial crown; beneath the overlapping metal structures, faint crimson-red illumination glows through recessed channels, casting subtle red reflections across the surrounding surfaces. A complex central metallic ornament descends vertically from the crown across the upper forehead, combining stacked mechanical segments, engraved filigree, circular joints, and a slender polished metal centerpiece. Her impossibly elongated neck consists of exposed biomechanical vertebrae, interlocking bronze plates, articulated joints, miniature pistons, bundled black cables, ribbed conduits, and delicate metallic tendons, forming a highly intricate mechanical column that seamlessly connects her head to ornate cybernetic shoulder armor. Flowing bundles of brass tubes and dark flexible wiring curve gracefully around the neck and across her shoulders, creating an elaborate fusion of organic anatomy and precision-engineered machinery, with tiny screws, recessed components, subtle surface scratches, tarnished crevices, oily reflections, and razor-sharp highlights enhancing the realism of every detail. Her shoulders are partially covered by pale, ceramic-like armor integrated with bronze mechanical platin
