How I did it....
The soil is plaster mixed with artists acrylic brown and loads of tea leaves added to give it texture, to this I pressed in / added the river bed with fine assorted gravel and larger rocks from a cinder type path, the grass is the normal modelling stuff and the water is Vallejo still water to make the stream, it starts in among the grass as a sodden boggy area then descends into the stream.
The bits I need to redo are the poppy rings and small crosses as they look terrible..but as only my second diorama, I'm happy

The engine is from a 1/24 Airfix Hurricane and has been cut away in bits to add the corrosion, and bits added to simulate some of the interior engine parts, the engine bearer has been chopped up and added, additionally bits of crushed thick metal foil (speed tape ) has been added to replicate parts of the wreckage.
The good thing is,the Hurri can be built minus the engine, so you get two models for the price of one
