First I mixed some of the background greens with ultramarine blue and raw sienna and covered the areas where the tape had lifted the background.

Next I added a small amount of titanium white to lighten the colour slightly and added a few more pines on the right side of the painting.
With burnt sienna I put in the middle area where a path runs through the forest.
Using raw sienna I put in some dead grasses below the trees and into the foreground on the left side.
Using various mixtures of Hansa yellow and cadmium red I scattered some leaves across the ground.
Using the white I added a couple of birch trees in front of the pines and the dark mix to add the markings onto the trunks.
Lastly, I used Hansa yellow and raw sienna for the leaves on the birches.
I am not happy with this piece and I will post this painting again at a later date once I have made a number of changes.
