Hope you'll like this little forest scene, As you can see : trees, grass, rocks (3xtypes), water, flowers(3xtypes)... forest!
For this one i used blender and a lot of botaniq add-on,The rocks and Trees geometry have been decimated so my computer wouldnt explode...The fog is basically a plane with b&w noise texture applied, connected to alpha and base color (color ramp used).
Hope you'll find it useful!
