For our first wash we will keep our values light. Start at the top of the page with Cerulean Blue and add water as you come down to the horizon line. Add some Aureolin to the blue and indicate trees. For the rocks use Burnt Sienna, Yellow Ochre, and Cobalt Blue. Put the color down and don't mix it. While the pigment is still wet, apply wax paper for the top. Let dry and remove. For the water use Cerulean Blue and water where the value is lighter and add cobalt blue to the button area. Let dry.
Our second wash we will focus on our middle values, adding more pigment and less water. Using Cobalt Blue and Gamboge indicate evergreen trees along the horizon line. Using Ultramarine Blue and Burnt Sienna start to define the rock shapes, trying to take advantage of the texture where you have it. For the reflections use the same colors that are above the water for the rocks and trees. Bring these colors down in a vertical manner and then with a flat brush, no color and just moist go across the area horizontally. Use the tip of the brush to show some movement in the water.
For our last wash we will be using our dark values. Winsor Green and Alizerin Crimson will make a beautiful dark value. Looking at your value study, indicate darks where shown for the trees. For the rocks add a little Burnt Sienna to the same mixture and add darks to the rocks (same thing for the water also).
