"Lipton was inspired by the religious paintings of the Flemish School. She tried to teach herself how to paint in the style of the 16th century Dutch Masters and failed. When traveling around Europe as a student, she began developing her very own peculiar drawing technique building up tone with thousands of fine cross-hatching lines like an egg tempera painting. “It’s an insane way to draw”, she says, “but the resulting detail and luminosity is worth the amount of effort. My drawings take longer to create than a painting of equal size and detail.”
