Hyper-realistic Biomechanical Mecha Warrior Bust AI Image Prompt

9:16 vertical, hyper-realistic biomechanical style. A frontal bust portrait of a mecha warrior, cropped from the shoulders/neck upward, occupying about 70% of the frame width, centered, with dark background negative space on both sides. The head is a full-coverage tactical helmet with a matte black metal shell, showing battle scratches and wear on its surface. At the center front of the helmet is a narrow elongated red optical visor with precise digital scales and scan lines inside. On both sides of the helmet protrude cylindrical communication modules and coiled metal tubes; these tubes extend from the back of the helmet down into the shoulder armor. The lower jaw is an exposed mechanical mandible structure with clearly visible metal teeth. The shoulders are heavy modular tactical armor in matte dark gray metal, with white stenciled numbers and red tactical markings on the shoulder armor plates. The armor surface shows signs of use, minor dents, and oil stains. The neck reveals an intricate mechanical cervical structure with clearly visible gears and hydraulic rods. Pure black background, with white UI elements overlaid on the image: a large numeric ID at the top, next to it several lines of small English tech text labels and warning symbols, and some characters with a slight glitch effect. The UI text floats on the screen as part of a HUD heads-up display. Lighting comes from above and front-left, fairly hard directional light — sharp cold white highlights on the helmet ridges and armor edges, with bright reflections on the metal tubes and mechanical joints. The face and shadowed areas sink into deep black, with extremely high contrast. Overall cool color tone, dominated by black, gray, and metallic silver-white, with the red visor and warning signs as accents. Ultra-realistic CG render texture, with realistic wear, grime, oil stains, and reflections on metal surfaces. Intricate mechanical structure with rich details such as tubes, screws, connectors, springs, etc. Shadow areas are transparent and not dead black. NO color, full body, background scene, cartoon, low precision, plastic feel, text watermark (excluding UI elements), human face, skin.
