A vertical smartphone-style weather poster for 成都, designed as a dreamy ultra-detailed miniature diorama cityscape under a bright blue sky. At the top center, place large bold white Chinese characters for the city name with soft 3D depth and a gentle drop shadow. Directly below it, center a fluffy white cloud icon made of rounded sculpted forms. Under the icon, add one line of smaller white text showing 2026-04-22 星期三, then a larger bold white temperature line reading 28° / 18°, then one more centered weather-condition line in white reading 多云. Keep all text vertically stacked, evenly spaced, and cleanly centered in the upper half of the image. In the lower half, create an enchanting hybrid city of traditional Chinese water-town architecture and a modern skyline: calm turquoise canals winding around tiny islands, 2 small arched stone bridges in the foreground, 1 pavilion on the left island, 1 tall multi-tier pagoda near the right-center, clusters of grey-tiled traditional houses and shopfronts, outdoor tea tables with umbrellas, lush willows, shrubs, flowers, and a few tiny boats on the water. In the distant background, show a contemporary skyline with many glass skyscrapers and 1 prominent needle-like observation tower. Scatter exactly 5 soft cumulus clouds across the sky including the central weather icon area, and add a few tiny birds for life. Use warm morning sunlight, cinematic atmospheric perspective, shallow depth of field, tilt-shift miniature photography aesthetics, highly realistic materials, delicate reflections in the water, and a polished whimsical travel-poster mood. Preserve a clean composition with generous sky above and the miniature city concentrated at the bottom, like a premium weather app hero image.
