I love the negative space in this drawing! The white paper provided the perfect base and is a powerful contrast to the dark details. In some ways it was a struggle to not touch the white paper and add more pencil markings. This was an exercise in self-restraint.
Of course the black spots required numerous layers of graphite and colored pencil. I added blue, purple, and brown to create depth. There are soft hints of pink around the mouth and warm rich browns in the eyes to create an additional sense of life. Quick short pencil strokes provide a fur-like texture.
