There are several challenges in doing a winter landscape. You have to making the show look real, dealing with the subtle and necessary value shifts and working for the soft texture you need to make the snow look nice and fluffy. So often it is not a mater of drawing the shapes, but shading in everything around it. Dealing with the negative shapes, which in this case are white or near white. One of the biggest challenges is finding your darks, and not being afraid of them. Shadows and shading are all important.
It was a snowy day in early March, one of those deep spring snowfalls that bring such a soft blanket of snow to the area. We had had a real storm, with thunder and lightning thrown in with the heavy snow cover. But the day these photos where taken had been a rather bright, sunny day so there are nice shadows and contrasts.
There are two types of shadow or shading going on here, the cast shadows from the sun and the contour shading you get with any 3-dimentional object, like the columns of the trees. Both are necessary to work this drawing. Since in this photo reference the trees now become the focal point, handling both shadows is very important.
Working the shadows
There are two ways to deal with these shadows. You can use softer pencils and rework these shapes, and you can use blending tools, like a stump or tortillion. Many blending tools are possible for any drawing. I tend to favor the judicious use of kneaded erasers. This seems to work especially well on snow scenes. Sometimes it is just as important to remove graphite, as it is to apply it
