Step 5: an opaque muted blue/violet was placed over the foliage where the shadow of the snow on the branches would be, and on the ground.
Step 6: A warm opaque white was put on the top of the snow caught on the branches, remembering that some of the branches would be facing you, and that the snow would be caught on the lower, larger branches. Tree tips are springy which allows the wind to knock the snow off the tops of the trees in short order.
Step 7: The entire painting was glazed with a neutralized quinacridone burnt orange in order to bring the whole into colour harmony.
Step 8: The background is begun with opaque washes. This step allows you to go back to refine the shape of your tree. Don't forget the interior 'sky holes' -there have got to be places for the birds to fly through!
Step 9: Some blue green and blue violet washes are added on a reverse diagonal to the twist of the tree.
Stay tuned for one more post for the finishing stages.
