CLEAN. When I was a young architect just out of college, I was working with an architect that designed very modern architecture, he asked me to design an elevation for a new discotheque we were building, and the sketches I came back with were, for his taste, very "scenographical" meaning, they looked too busy, like a theatre set. You see, in architecture slang, "clean" means simple design. (I think), this is a drawing of the way the final design of the elevation looked like, or at least that's how I remember it, you can see the finished project here:  varshiva nightclub 

I like the way the sky looks so "dirty" it could also work for the "opposites" theme of last week. This sketch was made with pencil and acrylics on watercolor paper.
