Space Engineers WIP: Seraphim

OK so I got Space Engineers a while ago. Had it lying around for almost a year. Anyway, I had this insane idea: Since I was already modelling hi-res versions of some of my older ships, knowing that the detailed interiors wouldn't be usable in XWA, I decided to use this game to accomplish that dream. While it's voxel based and therefore not as prcise as actual modelling I figured I might get somewhat close to what I was hoping to achieve, having fully explorable and yet pilotable capital ships.

And, me being me, I wouldn't just start with some small-time fighter or transport. Ladies and Gentlemen, may I present:
The Seraphim  ..... ooor "half" of it. As I'm grinding my way through building this ship (which I thought to be of a reasonable size) I come to realize how friggin' huge 900m are - and the work it's gonna take to build all this- with interior.
