with it's pointed edge in the smaller areas (his hair, eyes, eyebrows, nose, lips, cheeks, side of face, mouth, chin, neck, shoulders, and arm (T-shirt too). I will be using a pencil soon for darkening and very refined areas. I've lightened areas with the kneaded eraser like his whites, lip creases, and few hair strands. And I took a light gray pastel and gave highlights on his hair strands, reflective lights of his jawline and neck, and some hair on his forearm. I added dark gray to heighten the shadows in his neck area and on his arm and smoothed them in with a blending stump. Then I sprayed with "Krylon Workable Fixatif" to adhere the pencil & pastel to the paper for a non-smudging and workable surface.
