Honestly, I didn't give this the effort and time it needed, so any flaws like the light flicker and stuff are due to that.
@Mickey, With every one of my films I try to experiment with new building techniques, and the walls here are a result of that drive for uniqueness. I feared the jokes weren't going to be that funny, so thanks for proving otherwise.
Smooth the walls up, as in not exposing all of the studs? Yeah, that was my original plan, but I couldn't find enough of the right size tiles. And I tried hard to get a nice office hallway look with the potted plants, water cooler and coffee table, but what should I have done differently to help with that?
