Simple landscape. I made the base in Art of Illusion as heightfield. (Didn’t even know that ANT exists…) Tree and bushes are very basic Blender models, multiplied as hair particles. Cycles render. I try to improve this, but it seems to be strangely difficult… Maybe more tutorials needed. 
Try a texture for the ground that isn’t a uniform green. Forest floors are a mix of dead leaf litter and fallen twigs and branches, exposed rocks and dirt, and patches of green weeds with wildflowers in the sunny areas.
