I used pure raw sienna a washed in a background colour across all of the board.
Then adding French ultramarine blue and burnt sienna in various mixtures to the raw sienna I painted in background tree shapes. While the paint was still wet using the end of a brush I scraped out birch tree shapes.
Using various mixtures of French ultramarine blue and burnt sienna I painted in the area that I wanted to have my rocks and then scraped the shape out with a palette knife.
I will post this painting at a later date once I have added the markings on the birch trees and some leaves.
