hyper-detailed digital illustration of a mysterious cybernetic assassin, head-to-body ratio 1:4.5, standing in a commanding pose (0° vertical angle) wearing a dark hooded jacket (RGB: 20,30,80) with sharp metallic mask featuring glowing cyan eyes (RGB: 0,255,255, brightness 95%). Subject positioned centrally (X:0.5, Y:0.5) with perfect bilateral symmetry. Left arm extended at 40° holding an ornate energy sword with magenta core (RGB: 255,50,220) and silver-purple hilt embedded with glowing gemstones. Right hand displaying a floating emerald crystal (RGB: 50,255,100) radiating neon green energy with volumetric light scattering. Subject adorned with multiple layered gold chains (reflectivity 85%) featuring a large central medallion with intricate arcane symbols and glowing cyan core (RGB: 0,220,255). "SLAYER" text visible on dark shirt beneath partially-open jacket. Both hands covered in black leather gloves (reflectivity 40%) with multiple gemstone rings in precise ROYGBIV color arrangement, each gem emitting its own light source (3-5% environmental contribution each). Left wrist adorned with spiked metal bracelet (reflectivity 75%), right wrist featuring stacked cybernetic bands with neon accents (RGB: 0,255,200). Background features cyan wireframe grid pattern (RGB: 0,180,255) extending to infinity with perfect one-point perspective (vanishing point aligned with subject's sternum), creating 80-line geometric matrix. Complete retrowave/synthwave aesthetic with 80's-inspired digital realm composition. No natural lighting - illumination sourced exclusively from subject's glowing elements creating dramatic rim lighting (intensity 80%) around edges. Deep shadow core (density 90%) contrasting with neon elements. Render in ultra-high definition (8K) with ray-traced reflections, subsurface light scattering on gemstones (penetration depth 3-5mm), and volumetric lighting effects on energy emissions. Style combines cyberpunk aesthetic (70%) with dark fantasy elements (30%), executed in digital painting technique with high-contrast color theory application, Detailed digital illustration of a cybernetic assassin.
