Thanks for the comments, appreciated. I knew that this build wouldn't photograph well before I started and didn't plan or expect to make it past round one
I have several ideas for future additions, and I'd like to squeeze some in before the next Build Something. I've started casting a bunch of bookshelves and books so a library is going to happen at some point. I'd also like to make a command room with a 'holographic' table, at least one hangar, a cargo bay, some more sections overgrown with moss and slime, maybe some crew quarters and a scriptorium...
I also started a 3D Necromunda project (which will have higher walls) and it may end up being compatible with this layout, even though I made that using custom 2" squares to match the Zone Mortalis boards GW makes.
Too many projects in the backlog! I miss the days when I was just out of college, no kids, my job was one I could leave at the workplace... GW would come out with a game and I'd have a complete army (and themed terrain) painted and ready to go within two or three weeks. Ah, the good ole' days!
