Example

## Try an example

- Extend the scene on both sides into a wide panorama: the stippled blue halftone city keeps sprawling left and right with more towers, a distant bridge and thin radio masts dissolving into paper-white haze, while the dark grassy hillside continues under the figure's feet and drops away at the far edges. Same textured white paper sky, same blue-and-cream print palette, same cool twilight light and bokeh dots. The hooded figure, the hill and the original centre stay exactly as they are.
