When i saw poster for Episode 7 i instantly knew i have to build this one. Death Planet aka Star Killer Base. This picture is heavily photoshopped for effect, so take a look at the other one that is untouched except color corrections and scaling:

As seen here it is a little bit too egg shaped and looks much better after serious photo editing. It is fairly simple build using less than 50 bricks and there is not much you can do to those bespin halves.
