Actually wait a minute. I don't think swans quack :p
2 hours later, the swan has a bill and a hint of a head. Love using coloured paper, so much eaiser to work when you have a basic tonal value already there. I have had people tell me that its cheating using coloured paper when using coloured pencils. I don't get that, because its no different from painting a canvas to get a base colour. And looking at a bright white piece of paper can actually be intimidating, afraid to make a mark on the bright paper in case you mess up.
