Those mountains are looking soooo natural.. For me they are lovely! I dont know if would be good if u touch more displacements now, when it seems u found the G point of the mountains xDD
Displacement doesn't alter the colors, and it adds small scale detail and makes overhanging rocks.
To displace or not to displace. This is the question.

To me, with displacement it looks better as it adds more detail. But how about a slider for displacement rocks. It would give us greater variety and everyone just could adjust to his/her personal likings.
In general I'd like to have much more sliders for everything e.g. for wave/surf height, grass height, grass broadness, water sky reflection color, amount of daisies...

to create a unique appearance.
