What's interesting is I haven't used a pencil yet during this stage. I took a blending stump (since it won't leave lines and will cover a larger area) and shaded laying the stump tapered part flat (like a pencil) on his skin. Then I took it's point and “drew” with it's pointed edge in the smaller areas (like his eyes, eyebrows, nose, lips, cheek lines, beard, mustache, side of face, and mouth. I also used this application around his neck and t-shirt. I will be using a pencil soon for darkening and very refined areas. I've lightened areas with the kneaded eraser( lip shine, catch lights in his eye, forehead highlight, etc.
