It is simple but nice. I think you can get more out of this setup. Say you change POV to somewhere closer to the rocky bit visible and look a bit alongside it to the right, and decrease max slope for trees; you get more cliff. If you want that cliff more prominent or hanging over, add a surface shader between the terrain and compute terrain, add a twist and shear as a child and tilt everything a bit so the cliff hangs over (X or Z, -1 or +1, or a little less), but mask this surface layer by a soft circular/elliptical simple shape right above the cliffs. Play with sizes so only the cliffs hang over, the rest of the mountains stay as they are.
And add a little more variety in tree types.
