Fruit Trees Under Snow WIP 1

So I decided to choose this one for my January Monthly painting. I have painted it twice already, last January and earlier this month, and it has been a popular subject. It is 20″ X 16″ and I hope to retain some of the spontaneity of the original while using the advantages of allowing some drying time between sections.
Today I just painted background, snow-laden sky and snowy ground. I then etched in the skeletons of the trees to establish the composition. It may be a few days before I get back to this but I will post again as I progress.
