Here's a quick environment/lighting study I did for Artslam based on this incredible photo of Mt. Fitzroy in Argentina. I don't know who the photographer was, but I found the photo on this free wallpaper site, so I guess it's safe to use for educational purposes. Anyway, this is a lot like what I imagine the homeland of the mountain people in my world to be like. Vast, frozen, impossibly high mountain peaks with small, high-altitude valleys nestled here and there. Very nasty place, though the mountain people and their yaks and goats manage to do pretty well. Need to come up with a name for them...
