Using a dark mix of French ultramarine blue and raw sienna I put in the grasses with a little more detail on the closer field, leaving some areas of the white paper showing through which I will fill in later.

With light and dark mixtures of French ultramarine blue and burnt sienna I started painting in the trunks and branches of the three closest trees in the foreground.
I will post this painting again, once more of the trees have been completed.
