Cyberpunk noir woman in a smoky underground casino

A striking hyperreal cinematic noir portrait of a seductive 45-year-old cyberpunk femme fatale inside an enormous underground casino hidden beneath a dystopian megacity. The entire environment is rendered in dramatic black and white, with only intense crimson and molten-gold accents. She wears a glossy ice-white latex trench coat dramatically open into an exceptionally deep plunging neckline, emphasizing a voluptuous sculpted décolletage adorned with glowing crimson biomechanical circuitry tattoos. Heavy chrome chains, mechanical jewelry and ornate metallic ornaments frame her silhouette. Her platinum-blonde hair contrasts sharply against the darkness. Behind her, roulette tables, art-deco columns, smoky chandeliers, holographic playing cards and shadowy figures disappear into dense cigarette smoke. Bold crimson brush strokes slash across the monochrome scene like graphic-novel artwork. High-contrast lighting, hard shadows, wet reflections, subtle glitch artifacts, cinematic grain, dramatic close-up composition, hyperreal skin, Sin City-inspired neo-noir graphic aesthetic, ultra-detailed 8K, unified frame, no split screen.
