Yeah I can see that but it's a forerunner corridor, the roomba sentinels seemed to have kept them pretty clean until everyone else showed up . It's my first big interior dio so I learned a lot on it. The next will be a little more exciting with lights, more depth and such. I've always been amazed at the architecture of the forerunners.
If you search youtube for it I have a video of it " halo corridor" should bring it up. or just paste the youtube vid number 4A-36r0EMSM

Pretty cool diorama--I think a few barrels, crates or something littered about would have added to the display, as it's rather bare without the figures, but it looks nice as-is too.

I've always been envious of custom dio's and this is a great one, very clean and well scaled. Awesome work!
