This piece works with shadow art, which I find very interesting. I love pieces with crisp lines and the affect of the nails has exactly that. The contrast between the white wall, dark nails, and light shadows is dramatic, yet simple.
LIGHT: This is a photography of a hallway in a cathedral. There is very white, visual light shining through the windows which creates shadows on the floor. The design is very clear and simple because there are no colors or any disaccords.
