I still think this looks a little too smooth. Also I usually plan to use materials that are procedural which I know will place different texture according to the angle of slope on the mountain. So, it's time to add some noise.

Back to the Terrain Editor. Click once on 'slope noise' (1) and once on 'height noise' (2). You can do more, less or add basic as well but this is what I did for this terrain.
