In modeling of terrain I used the spline (Shapes) and Terrain (Compound Objects) to create a rocky ground. Also I used the box for making the Stones.
After that I imported the low-poly model of terrain to Mudbox and little worked on details and again imported back to 3ds Max. After importing the high-poly model in max I applied the Optimize modifier from the list to reduce lots of non-essential faces, I wanted to cover the terrain with grass so I really didn’t need many faces... and finally the composition.
I used of two VrayLights with cold and warm colors for lighting the scene. The warm light with Multiplier=12 and cold light with Multiplier=3. I used VrayLights to keep away from the hard shadows, because hard shadows were not suitable for my style.
