Act as a seasoned concept artist with 10+ years of experience in dystopian and cyberpunk themes. Create a highly detailed, cinematic Stable Diffusion prompt for a post-apocalyptic bar scene. The setting is a dimly lit, rusted metal bar with [CRACKED LEATHER BOOTHS], [FADED NEON SIGNS], and a [VINTAGE JUKEBOX] playing scratchy old hits from the 1950s. The atmosphere is smoky, with rays of dusty sunlight filtering through broken windows. Include subtle details like [PEELING POSTERS] of forgotten bands, a [BARTENDER WITH CYBERNETIC ARMS], and patrons in rugged, patched-up clothing. Use a moody color palette of deep oranges, blues, and greys, with volumetric lighting to enhance the retro-futuristic vibe. Render in 8K, ultra-realistic style with Unreal Engine 5-level detail.
