I always carry a pocket-sized Moleskine sketchbook and a pen. Between 2007 and 2012, during my commute to and from work, I created a collection of quick feet sketches. This series of sketches from the New York subway was unlike anything I had tried before. It was live drawing in a chaotic environment—during rush hour on a packed subway train, surrounded by hundreds of people heading to or from work. It was fueled by pure adrenaline, constant noise, and the constant movement of people getting on and off the train. I created most of these drawings while standing, leaning against the door, and using the brief window of time between one station and the next.
