Ok, so now the paint is dry lets get on with the trees. These are conifer trees and are adapted to snow conditions so their branches are generally downward sloping to facilitate the snow sliding off them. Some of the branches are pointed upward towards the sun but as they lengethen they droop especially when the snow burdens them. The first trees I'll put in are the distant ones. Because they are further away they are more blue- see as things recede the warm colors -yellow and red-diminish until a faint blue occupies the feature. Here I mix the alizarin red with the ultra blue and a spot of white and use the pastry brush.
The closer trees have more mass and color. I use a yellow ochre with the ultra blue on top of a deeper color from burnt sienna and ultra blue. The scraggly bit of foliage to the right is in preparation for the trunk. Now I ask you ....can you see the distance operating on color, tone and detail! Of course you can. That folks is the simple concept of aerial perspective at work. Easy aint it!
