The art is very intricate and he gets the colors by scraping off the top paint and revealing what's under it. Usually the white Masonite which he paints on. He first covers the canvas with Kilz of all things. Then he goes one section at a time, putting a paint color on, letting it dry then covering it with another color, which he scrapes off to show the color below it. It's tedious work, but I can see how it may be very relaxing. We joked about him falling asleep while he's painting.
You can see the detail here and imagine the hours that goes into ever piece.
