biomech, a 3/4 angle close-up portrait of a dark cybernetic warrior wearing an ornate biomechanical mask. The mask is made of polished obsidian chitin shells and exposed mechanical joints fused with weathered, desiccated human skin texture. Vibrant bio-luminescent plasma nodules run along the jawline, casting a high-contrast emerald-green glow onto the armor segments, cinematic smoke, heavy shadows.
