I started with a darker blue in the top of the sky and gradually lightened the colour with water as I worked lower.
When I reached the horizon line, I decided that it would be a snow scene and I put a few shadows across the snow.
Cerulean Blue

I kept the painting darker at the top of the sky and gradually lightened it as I approached the horizon line.
Using horizontal lines I indicated a lake using a medium wash of blue, followed by putting in the waves with a slightly darker blue and lifting highlights with water.
Ultramarine Blue

Into the sky I brushed various strengths of Antwerp Blue with diagonal strokes, trying to give the illusion of cirrus clouds.
I left a small area of white just above the horizon line for mist rising off the lake; and below it I used horizontal strokes to indicate the almost calm surface.
Antwerp Blue

I started with a darker mixture into the top of the sky, leaving some areas white and softening the edges of the clouds.
As I worked lower in the sky I lightened the mix with water.
I put in the lake with a combination of the light and dark blue colours.
Cerulean Blue and Antwerp Blue

Once again I used diagonal strokes to create cirrus clouds, keeping the top of the sky darker and lightening the colour toward the horizon line.
I wanted this piece to be a snow scene, so I left a small line of white, followed by running shadows across the snow.
French Ultramarine Blue and Antwerp Blue
I will post each of these paintings at a later date, once more work on them has been completed.
