Daily watercolor - A Green World

Started painting the watercolor painting A Green World.  It is on a 15 x 22 inches (half sheet) cold press Arches watercolor paper.  It is lots of fun doing the backgroud and green leaves of the plant always keeping the value in mind.  I know that the challange of this painting is to have different shades of green next to each other keeping in mind the separation of value between them so as to have them distinguish between each other in the painting.  Another challange I found is to keep the darker shade interesting by doing it in a variety of color shade but not make them turn into mud.  A layer of wash one after another is used for the dark shadows as well as the lighter ones.
