The most fun of 3D modeling is to create an scene as realistic as possible, so a big part of that contains a realistic digital environment,
I always use Vue Xstream for this kinds of scenes.
It is fast, easy to render and very realistic, if you need water, trees or landscapes you can realise it all.
Used Vue Xstream Techniques:
Procedural terrain, High field Terrain, painted materials, trees, stones etc.
Render with a direct Sun light.
