Here in the next step, I have defined the tree branches using a mix of permanent green and raw umber with a touch of yellow ochre. I have also added a slightly darker tone to the snow shadows higher up and brought some of that color down to the mid section of the tree. Using a warm white (mixed from titanium white and yellow ochre), I start to put in the highlights. So far I am satisfied that I have capturing the characteristics of this tree. I especially like the way that it leans uphill and it is obvious which direction the storm came from.
