To Green or not to Green

After watching Star Wars Revelations, I began to realize that I had seriously restrained myself with visuals because I did not want to worry about green screen shots. But the other night as I was looking through my sketchbook, I found a sketch of an old statue (monumental in size) that was leaning at a slight angle with rain water flowing from the empty eye sockets like waterfalls. It was to be the location of the librarian (who in the storyboards lived in a makeshift tent). That could so easily be green screened in. I have a lot of photos from the locations so I think I am going to try to create the image and perhaps edit it to see how feasible it could be.
