Create an photo capturing the majestic and vibrant London skyline at dusk. The scene should be photorealistic and rich in detail, with the last glimmers of the sunset casting a warm glow over the city. Iconic landmarks such as the Shard, the London Eye, and the Houses of Parliament should be silhouetted against a sky painted with hues of deep purple, fiery orange, and dusky pink. Lights begin to twinkle along the River Thames, reflecting softly on the water's surface, while the bustle of the city transitions into the calm of the evening. --v 6.0
