Cool! This is looking very good. Great choice of environment to model. I love the detail and the feeling of depth. I just feel that some of the surfaces are letting it down just a bit - such as fire extinguisher, seats and table top. Also I am not sure if I am buying the planet at the moment - It just looks a bit fake - maybe some clouds and a slight bump map might help.
But those are minor problems - overall this is a great model - nice to see something slightly different. Well done Wishbonekenobi
