Create a stunning illustration of a futuristic cityscape at dusk, where the sky transitions from deep blue to a gradient of purples and pinks. The artistic style should be a blend of cyberpunk and sci-fi, with intricate details and a high level of realism. Use digital painting as the medium to achieve a polished and vibrant look. The background features towering skyscrapers with neon signs and holographic advertisements. The foreground includes a bustling street filled with flying cars and pedestrians in futuristic attire. Reflective surfaces on the buildings and vehicles should capture and amplify the neon lights, creating a mesmerizing effect. Use a wide-angle lens perspective to capture the vastness of the city. Apply color grading to enhance the neon hues and a subtle HDR effect to bring out the details and contrasts. The lighting setup should include a mix of natural twilight and artificial neon lights, casting dynamic reflections and shadows.
