I love this graphic style by Jose Guizar entitled Windows of New York.
The Windows of New York project is a weekly illustrated fix for an obsession that has increasingly grown in me since chance put me in this town. A product of countless steps of journey through the city streets, this is a collection of windows that somehow have caught my restless eye out from the never-ending buzz of the city. This project is part an ode to architecture and part a self-challenge to never stop looking up.
