Grey Cat- As far as size goes, in modern day terms for a scale that is marginally understood. Think Super-Tanker big, obviously since this is a starship it would be far bigger but in a relative way as far as scale goes a supertanker would work. The prop forperson asks at what poser relative scale you would like (like ground plane wide, or double?) Like for corridor sections would you like double long, or a combination of section sizes?
