Quoting Gab BOIDOT
Nice test ! For me you can go further with a bigger one, and maybe in a less dark color.. You're still surprising me with your mocs !
I did try dressing it in white first, but since the new uploader uses white as the backdrop, the results looked very washed out and difficult to pick out detail. I did also try using lighter shades of grey on the walls, but I felt the metallic grey said "starship hull" better.
I'm going to attempt something much larger next time, when I tried placing some of my mocs in this as a test, anything more than 3 minifigs tall was looking over the walls!
Maybe something with a door next...
