The theme is the tranquil lake surface and the afterglow of the sunset. In the center of the image is a wide lake surface, shimmering with golden light under the reflection of the sunset. The trees by the lake and the distant mountains present beautiful silhouettes in the afterglow, creating a serene and majestic scene. The font design is simple and elegant, using gold or dark tones to contrast with the lakeside scenery at sunset. The entire poster is filled with romance and poetry, allowing one to feel the beauty of nature and the power of tranquility. --ar 2:3 --v 6.1 --stylize 100
