The subway stations in Washington DC have some great geometric designs. They might just be concrete but I love the look of them especially with the shadows thrown up by the lighting. Going out to a restaurant one night, this scene caught my eye, with people waiting to board the train and the blur of people getting off. I did this black and white version to particularly emphasise the shadows created by the lighting.
