Here's a couple of pieces I can show from the last project I was on - Space Siege. The ship is called the I.S.C.S. Armstrong and as you can tell from the scale of the Eiffel tower, it's huge! This is a ship designed to be a deep space colonization ship.
I had in mind that a person could be born and die on this ship without ever stepping foot on a planet surface. The atrium centered at the 'eye' of the ship could hold the Eiffel Tower inside it. I have some concepts rendered of those too that I will post later when I'm allowed.
