Cheers mate i do use the blue prints, surland.com etc, but good ones are hard to find, and some are more interpreted than others, whatever blue prints are used i find it best to collect lots of reference then tweak the model by eye afterwards. You are correct about the lighting. Star wars is quite a lot darker than i seem to remember when i go back to it now, however they do cheat like mad, and there is bounced light everywhere! Still its going to be a tricky ballance to strike between the look of the film and realism, thanks for the comments.
