This image was modeled and rendered completely in Cinema 4D, very little post work in Photoshop. The basic scene did not change much after the initial set up. I probably ran up to sixty test rendered until I was able to come up with an image I was happy with. All of those changes came in the lighting set up. This final render is using a single light which is cast on the character through the window. At one point along the way I experimented with some fill lighting but preferred the more natural effect of a single light.
