Each painting that Armstrong creates is the product of meticulous process. The artist embarks on various excursions to explore Los Angeles at dawn and dusk.
Sometimes travelling no more than a few miles from his home, Armstrong camps out at different viewpoints to take hundreds of photographs of the same scene.
At times, Armstrong creates drawings from these many photographs, using them as starting points for his canvas works. At others, he dives straight into painting, spending more time on underpainting to plan his compositions.
