Create a stunning visual of a graceful swan gliding smoothly on the shimmering surface of a tranquil lake as the sun sets. The sky is adorned with a cascade of warm hues ranging from soft pastel pink to brilliant orange melting into deep crimson and violet. The waters mirror this celestial spectacle, creating a kaleidoscope of colors around the swan. Surrounding the lake, the silhouettes of trees stand as silent spectators to this captivating scene, with the peaceful ambience being occasionally disturbed by a gentle ripple or the call of a distant bird.
