Diorama

A diorama places a finished model into a small built scene, whether that is a patch of cratered ground under a tank, a runway apron beside an aircraft, or open water under a ship, so the subject is shown doing something or existing somewhere rather than sitting alone on a plain base. It turns a single model into a small piece of storytelling, and it is as much a craft in its own right as the model building that goes into it.

Groundwork usually starts with a base, built up with foam, plaster, or dedicated groundwork products to form terrain, then textured and painted before scenery like grass, rubble, or water effects goes on top. Keeping every element, from figures to vehicles to background props, in the same scale is essential, since a diorama is one of the fastest places for a size mismatch between kits to become obvious.

A common mistake is overcrowding a small base with too many elements competing for attention, when a simpler scene with one clear focal point usually reads better and finishes faster. Another is neglecting the groundwork entirely in favor of the model itself, when a flat, unconvincing base can undercut an otherwise well-built and well-painted subject sitting on top of it.
