The cast shadow across the snow bank and the ruts of the road can be very convincing if you bear in mind one important principle. The main thing to remember is that the cast shadow hugs the surface of the forms, and these forms are very much like a group of cylinders Iying side by side. So wrap your strokes part way around each form and make them drop down into the crevices and then curve them up over the bulge of each ridge.
Shade the left side of the building with the dark gray chalk. Trim the end of the chalk to a small chisel point on the sandpaper. See small sketch above. With the dark gray chalk cast a shadow from the building, following down the slope, across the road and into the ruts. Draw the boards on the front surfaces of the building with the light gray chalk. Draw the rectangular windows and doors then put another dark accent under the eaves with the carbon pencil. With the dark gray challc cast the tree shadows across the front of the picture, down the slope into the ruts and up the opposite slope, each stroke growing narrower toward the left. Also make a broad Qst shadow across the front of the picture. Blend with the tip of the paper stomp and darken the ruts in the shadow with a pencil. Draw several pine trees beyond the house, starting with vertical lines and sloping the branches down in shaggy, triangular shapes.
