Using a mix of French ultramarine blue and burnt sienna I put in all the tree trunks first. Raw sienna was added to the trunk colour and then painted into the foreground.

While the paint was still wet I dropped in a little bit of pure new gamboge to create interest.
With a sponge and mixes of raw sienna, alizarin crimson, cadmium red new gamboge and cadmium yellow I added the leaves onto the trees.
Into the dark foreground I put in splashes of bright colour withe cadmium red and cadmium yellow.
