This is not a drawing or painting but rather scratchboard. The scratchboard panel is a 1/8" thick board coated with a special white clay and a topcoat of black India ink. Using any sharp instrument, I scratch off the ink in various patterns to reveal the white clay and form an image. It is one of the most difficult art mediums because it is unforgiving if one makes a mistake. You can't erase or paint over an error. I used a few different tools to scratch this piece. My main tools were a #10 and #11 scalpel. I added color with acrylic ink washes.
Harimau is the word for tiger in Indonesia. This particular one is a Sumatran Tiger. It is critically endangered with less than 400 remaining in the wild.
