Act as a visionary concept artist with 10 years of experience in creating futuristic urban landscapes. Design a breathtaking cityscape at night, illuminated by vibrant neon lights. The scene should depict a sprawling metropolis with towering skyscrapers, [sleek flying vehicles] zipping through the air, and [holographic advertisements] casting colorful glows. Include intricate details like [glass walkways] connecting buildings, bustling streets filled with diverse pedestrians, and a mix of futuristic and retro neon signs. The atmosphere should feel alive, blending cyberpunk aesthetics with a sense of wonder and advanced technology. Use dynamic lighting to emphasize the contrast between the glowing neon signs and the dark, moody sky. Ensure the composition feels immersive, drawing the viewer into this high-tech, nocturnal world.
