For a year, I traveled the same train route for work, sketching the people I encountered during my commute. The train became a world in motion, where different generations and cultures meet, their lives intersecting for the brief span of a journey. Flipping through the sketchbook feels like watching a movie: young nerds glued to their keyboards, a rapper lost in music with his headphones on, workers unwinding, and lovers seizing the moment to be together.
