I am beginning to add color now to the wolf. I strengthen the darks with black and sepia. (I am using Polychromos which are a hard pastel). I also add some warmth with a brown soft pastel.
I have also added some ultramarine blue in the shadow areas of the wolf. And the white is added in the lights. At this stage I am being very careful not to apply the pastel heavily. The papers tooth will quickly build up and then no more pastel can be added. At this early stage it pays to be careful!
