Act as a visionary concept artist with 10+ years of experience in blending vintage aesthetics with sci-fi elements. Create a striking Midjourney portrait of a [retro-futuristic gangster] wearing a [gleaming chrome-plated fedora] with built-in [holographic visor technology]. The character should have a [smoldering cybernetic cigar] emitting neon smoke, a [silk pinstripe suit with LED thread detailing], and [augmented reality tattoo sleeves] displaying shifting 1930s mobster motifs. The background should be a [rain-soaked neon-noir cityscape] with floating vintage cars and art deco skyscrapers. Use dramatic chiaroscuro lighting with [pulsing magenta and cyan accents] to emphasize the character's mysterious demeanor. Render in hyper-detailed 8K resolution with a cinematic aspect ratio of 16:9, blending dieselpunk and cyberpunk influences seamlessly.
