The clouds were the most difficult part of the entire render. Eroding the entire terrain was actually the easy part, even down to the alluvial run-offs over the basin. For the clouds, i wanted to see detail in the formations and how the light scatters inside of the clouds. Originally i did go softer but i was lacking details i wanted to see. Of course i can always alter the clouds again for a more softer look and try and keep the details i want.
