The idea behind this doodle was a simple one, to take the same geometry and from it make 2 scenes by changing just lights and materials. (I actually made a third as well but its pretty borrring to look at so I've left itout.) Why? well just for something to do really on a sunday evening to relax and I wanted to try something else as part of my enviroment pipeline.
I'm more partial to the 1st image as it has a more 'alien' feel to it.
