After wetting the paper, I first brushed raw sienna into the sky using sweeping strokes and leaving areas of white.

Next I used burnt sienna and I brushed covering some areas of the raw sienna and still left a few areas of white paper in the sunset sky.
Once again I used horizontal strokes to indicate the water, being sure to leave some areas of white paper and raw sienna showing.
Mixing a grey with French ultramarine blue and burnt sienna, I swept in some clouds into the sky and the distance shore and an island.
With a slightly darker mix of the grey I brushed it into the water.
Once the paint had dried I lightly indicated where I would place my foreground trees on the shore.
I will post this painting at a later date once some work has been completed on the trees.
