The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.

Prompt

An isometric diorama of a single city block, presented as a floating object with a clean cut earth base. True isometric projection with no perspective convergence, soft even lighting with gentle ambient occlusion, a restrained palette of warm stone, sage green and dusty blue. Small details: a corner shop awning, two parked cars, three trees, a figure on a bicycle. Plain off white background, soft contact shadow.

Tips

1Say true isometric with no perspective convergence or you get a three quarter view.
2A cut base turns a scene into an object, which is the whole appeal.
3List three or four small details. More than that and the block gets noisy.
