This one is quite special to me as I am a massive fan of sci-fi. And one of the core aspects of sci-fi is definitely its architecture. Though they vary greatly from an artist to another artist's perspective. This might take the form of different themes, some might be appealing to the eyes some might be great for the needs of modern communication. There's a lot of types that can be found. But the correct one can only be decided when the time has arrived.
