After ages I was working on something new and heck, personal work is so fun.
This interior concept is called Terran Assembly. I imagined how an international planetary council might gather in the near future, once humanity begins to see itself less as separate nations and more as a shared civilization on Earth.
The chamber is located in orbit and overlooks the planet itself, constantly reminding its delegates what they are representing.
The sweeping curves represent the 6 nation conglomerates, emerging out of the central speaker area, forming a union.
