天空的选择：一张图的一半在天上

Create an architectural visualisation in which the sky is treated as the most important compositional decision. Show a sky with genuine structure rather than a smooth gradient: layered cloud at different altitudes, a break where light comes through, and a tonal shift from darker at the zenith to paler at the horizon. Detail the cloud as consistent with the light on the building — if the sun is low and from the left, the clouds must be lit from the left with their shadowed sides turned away, a match that is frequently got wrong. Show the sky's brightness as correctly related to the ground: bright enough to feel like sky, not so bright that it blows out. Detail the horizon with a slight haze band where the sky meets the distant landscape. Show the composition giving the sky at least half the frame, with the building placed low so it sits within a large atmospheric field. Keep the sky's colour informing the shadow colour on the ground. Photorealistic, sky-dominant, atmospheric, low wide view.
