I'm back from my holiday- I had my laptop with me while I was away, so I could make some new shaders, but I had no computing power to make actual renders.
I tried to make new textures based on Iceland's volcanic landscapes. So darker, sometimes colourful basalt rocks , grey sandy parts, some snow, and mossy islands, greenish volcanic lakes and some magma.
(Still rendering the latest one with the magma lake)
I will ad some ground fog and better snow, and experiment with the lighting. There's a few layers of fakestones, but no displacement on them yet.
