The drawng is from a copy from a book that presumably deals with fractals from nature...I do not know since I found this bit of paper lying around at my place of work.
I was admiring the darks and grays and lights and my new feathers, when I had to put my sketchbook down to attend to something else. Alas on a messy table with some water on it as you can see! My first reaction was to curse the ink-maker, because the tiny bottle did not say that the ink was not waterproof.
But as the paper dried out, I could see the stains (which I quite like) and which bring a dynamics into the drawing. What sometimes seems to be negative in the beginning, could end well after all!
Much light!
