Thank you Ulco and no...that is your expertise
It is a very basic texture applied with surface layers with slope restrictions.
Not everybody likes those kind of images but i love them.
I tried it before but getting the image scale right is trial and error mostly.
For me at least. And without postwork (the most important was over sharpening) it doesn't look the same.
Below are the textures i used for the two images and one of the original render output (from the last test) if you are curious how the raw render looks.
As you see quite a hard work
[attachimg=1] [attachimg=2]
