On a recent Cinema 4D project I was going for a low poly look. In order to learn a bit more about that style, its technical demands and hurdles I did some quick layouts for some private greeting cards.

I only used some landscape objects, one plane and several spheres (within a MetaBall Object). A fairly simple setup with some hours of tedious tweaking to get the shapes and shadows right. In the end I rendered several passes for the mountains, clouds and sky to composite in photoshop, where I also added the type.
