Landcape watercolor painting - Fog

Started this landscape watercolor painting in which I have outlined the landscape using pencil on a 15 x 22 inches of cold press Arches watercolor paper.  Using Burnt Umber I painted the underpainting making aware of the different shade and form of the painting.  Because at this stage there is no color pigment involved, more focus is on the various tone of the areas as well as the shape.  Burnt Umber is the only color pigment I use at this time on the watercolor painting.  Wet in wet technique is used to do a quick underpainting of the whole painting leaving white areas exposing the whiteness of the paper.  Next stage will be using various colors for the foggy background and water reflections.
