I started this page in the sketchbook with a quilting motif, called a feather. Then I just started adding doodly details, one at a time.
I really like the result and the graphic feel of the black and white. (The drawing book really does have a slight gray cast to it, though)
I might try copying this and making the paper appear more white. Then, adding colors found in peacock feathers would really bring it to life.
