Generate a beautiful background illustration in the style of Makoto Shinkai’s animated films. The core scene is: "{argument name="scene" default="a railway crossing in full bloom with cherry blossoms"}", but the focus is not on characters; it is on the environment and the atmosphere of the sky.

Use a wide 16:9 composition, as if it were a single frame taken directly from a Shinkai movie. The sky must be the absolute protagonist, occupying most of the frame. Paint an extremely spectacular, detail-rich sky: for example, a towering cumulonimbus cloud stretching to the heavens, or gorgeous evening clouds where orange, purple, and deep blue gradients interweave, or a huge rainbow arching over the city after the rain. The lighting should be at the most magical time of day, either Golden Hour or Blue Hour. Include strong yet soft lens flares in the sky, with sunlight streaming through gaps in the clouds to form clear volumetric rays, and tiny glowing dust motes and light particles drifting in the air.

For the ground and environment, render the {scene} in near photo-realistic detail: carefully depict utility poles, complex webs of power lines, road signs, traffic lights, vending machines, distant skyscraper silhouettes, and the small traces of everyday urban life. If the scene includes rain or puddles, the ground should look wet, reflecting the colors of the sky and nearby lights like a mirror, filling the image with a transparent, cool atmosphere and a sense of slight humidity.

In terms of composition, use a wide-angle, large-scale view to emphasize the grandeur of the environment and a strong sense of depth, making the viewer feel like they are looking up and being swallowed by the scenery. If there are characters in the image, they should be tiny silhouettes or back views, standing at a street corner, on a rooftop, or by the railway, gazing at the sky or the distance. Their small figures should enhance the sense of story, loneliness, and imagined future, without stealing the spotlight from the environment.

The overall color should be clear and saturated but not harsh. The contrast between light and shadow should be strong yet still soft, with enough detail that the image can be used directly as a desktop wallpaper. The style must clearly carry Shinkai’s signature sense of romance and transparency, rather than a heavy oil painting or pure photographic realism. High-resolution illustration, 16:9 widescreen ratio.
