I am working on a series of watercolor illustrations of the four seasons, inspired by the enduring works of Alphonse Mucha. A friend on Facebook posted this great online tool, so I thought I'd give it a try. I love the results!
Here is the web link to Harmony, a procedural drawing tool web page. Just select at the top which brush you'd like to use and then start drawing in the white area.
