Invented cityscape. For those familiar with architectural styles: it's like Piranesi meets Sant'Elia. Not that I chose those two styles on purpose. I just had an idea and started drawing, and it evolved into this.
I had read a book on the italian interbellum architects Terragni and Libera recently, so apparently that futurist/rationalist/Mussolini building style stuck in my mind. Just drawing for fun.
