Construction workers

Sketching through a window and feeling like a spy, I sketched these construction workers. The fresh mix of concrete was transferred from the street floor to a house's second floor through a series of orchestrated movements of a construction workers' team. One of them filled buckets with concrete, two more carried it to the forth worker who was pouring it on the second floor while a fifth one spread it. Lots of muscle moving rhythmically like a song, a song I could dance to the rhythm of my pen.
