I mixed various different greens using Antwerp blue, burnt sienna, French ultramarine blue and raw sienna.

With some of the remaining greens I added the ripples in the water below the horizon line and the reflections below the island.
Next I put the grasses in with raw sienna.
Lastly, I used the dark green and added some alizarin crimson and put in the tree trunks, branches and a few dead trees.
