Like the rocky outcrops, just like my home country, New Zealand. If I'm right, they filmed some of the Hobbit there. As for reference material, thinking about it now, why not use pictures from New Zealand?
I have used New Zealand for reference before. Although, I mostly just type in New Zealand and look at a bunch of amazing landscapes to fill my visual library with-- and most times something in there inspires me to create a New Zealand -themed landscape. Haven't really created one like that yet though.
I wish I lived in New Zealand by the way. Such an amazing place. ;_;
Ahh I see . Well maybe you can ask me what sort of terrain you want then I can suggest places that have that kind of terrain . For instance, southern alps for snowy mountains, or Rotorua for geothermal things. etc
