Generate a visually stunning, highly detailed image of a sprawling futuristic metropolis at twilight. The scene should feature an intricate network of illuminated aerial highways bustling with sleek, numerous flying vehicles. Dominating the skyline are towering, translucent crystalline skyscrapers that pierce through atmospheric, neon-lit clouds. These architectural marvels are adorned with dynamic, vibrant holographic billboards displaying abstract patterns and corporate advertisements. Use a wide-angle, low-angle perspective to emphasize the immense scale and advanced technological grandeur of the city, with a subtle glow emanating from the urban infrastructure.
