I did repeat renders and results were identical. Shifting the light would change things. Sometimes better and sometimes worse. Composition is a whole separate issue and I only tried a rather limited set of possible combinations in order to keep the number of tests down to something reasonable yet large enough to explore the issue. Lighting is crucial in most images (real and synthetic). I want people to understand that C can produce really impressive results and knowing what it's doing and how you can manipulate it to make results you want is important. Glad you liked the writeup. -Kix
