Here is a quick watercolor study of kittens. I have a book I started writing more than a decade ago, and eventually I would like to finish it and illustrate it myself. Its characters are my three cats, Miniver, Beatrice and Dante, when they were small. (They are 14, 13, and 12 now, which gives you an idea how long it's been since I had this idea!)
The challenge is to paint black cats in watercolor and give the impression that they are black without using black. (My watercolor teacher would never let us buy black--we had to mix our colors ourselves and make our own--and also realize that black isn't really black, it's a whole bunch of colors that combined give the impression of black.)
You'll probably see more of these here as I get back to the story.
