Ink outline watercolor landscape painting

This is the progress of the watercolor landscape painting of British Columbia coast line I have started.  I have started with a under painting and then various watercolor pigment was added on top in layers.  Now it is the addition of ink outline.  I have used a Sharpie Permanent Marker to do the outline of the landscape watercolor painting.  I love this step because it defines the shape of the landscape in the watercolor painting.  The ink outline  is freely drawn with often reference to the photograph I took of the landscape scene.  Next step to this watercolor painting is to add more layers with watercolor pigment within the boundaries of the ink outline to create a more interesting and colorful watercolor painting.
