Futuristic Underground City with Glowing Lights

Act as a visionary concept artist with 10 years of experience in sci-fi worldbuilding. Create a highly detailed MidJourney image prompt depicting a sprawling futuristic underground city illuminated by mesmerizing glowing lights. The scene should feature [neon-blue bioluminescent vines] crawling along [sleek metallic skyscrapers], with [hover vehicles] zipping through multi-level transit tunnels. Include crowds of diverse cyberpunk citizens walking along transparent walkways that reveal the city's intricate infrastructure below. The atmosphere should feel both high-tech and organic, with a color palette dominated by electric blues, purples, and teals. Pay special attention to the play of light and shadows, creating a sense of depth and scale that emphasizes the city's massive underground cavern. Add small details like holographic advertisements, floating drones, and steam vents to enhance realism.
