A play of shadows, marks the path of a brook, which flows inside a dense forest and the light reflects, like a mirror, its transparent waters.
Here is an interesting basic environment for your scenes. It's light and easy to handle.

Attention: This scene is available only in blend format and it's not suitable for being migrated to other programs (due to the particle system used for ecosystems).
However, you can use the heightmap in tif format (in the packlist) and use it with the displacemet feature in other programs.

Notes: The scene include 2 simple terrains (1 core and 1 background), modeled in World Creator 2 and texurized in Blender (Render Cycles).
The terrain-core was populated with 7 eco-systems (by ParticleSystems). All the assets are in bundle (1 tree, 1 dead leafs, 2 shrubs, 3 rocks, 3 pebbles, 1 grass patches).

Packlist: 1 Blender file, 2 textures, 8 alpha-masks, 1 heightmap.tif (16bit), 1 readme.pdf.
