How I paint a Winter Scene

I have been trying various techniques to paint snow with pastels. Each technique and paper type leads to a different look to the finished painting. I am enjoying the results I am getting with a value underpainting. This photo shows my set-up. You can see my reference photo and thumbnail sketch. I am using UArt paper. In thisphoto I have applied Nupastel and a dark Terry Ludwig pastel. Next I will brush this in with alcohol and wait for it to dry. This gives me a nice road map of values to follow which helps my snow stay bright, crisp and clean.
