Cameni, it seems you really touch some magic key.. Those mountains look like mountains now. Of course they can have more erosion, etc, for being so tall mountains, but atleast look much better now than before. They look more real.
I always had the thinking, the textures and colors in mountains was not matching perfect with the mesh, and sometimes it was something messy. Not natural
You know what they only need now? A new snow layer, or ice layer, that can get in action in some heigh you can configure, in adition with the normal snow we have now. This ice layer can have the ability of keep in the rocks in almost 90º angles. And being ice in high altitude, can be a bit diferent from the snow, more blue, etc.
Then we would have the himalayas almost like real.
I have a list of ideas that i want to post soon. So i will add this idea too )))
