I started by putting in the shadows across the snow with a mixture of Antwerp blue and French ultramarine blue.
Next I added a little bit of burnt sienna to the shadow colour and put the first layer of pine needles on the trees.

While the shadowed needles were drying I added a little bit of raw sienna to the green mixture and the high lit needles were painted.
Next I mixed a grey of French ultramarine blue and burnt sienna and put in the tree trunks and branches.
Lastly, using mixtures of raw sienna, burnt sienna and new gamboge I put in the grasses and growies.
