Folk Art Tree sketch

I wanted to draw a tree in a more folk-art style here, with large flat areas to be filled with bright saturated color. This kind of design would probably translate well into printmaking or embroidery. I am always surprised that these style paintings fill up the 20 minute timeframe - I could easily work on this for another 20 minutes to get deeper color and more detail. Pen and watercolor, 5 1/2" x 8".
