When I first started painting, my Parisian aunt was very happy because she loved art. One of the first things I sketched was a copy of a Don Quixote sketch by Picasso that hung in her living room. She liked it and encouraged me; one thing she drilled into me was to go outside the lines, to loosen my grip. It took some practice, and it's probably the best lesson I learned.
I'm a dog person. But I love sketching cats! Meow.
