Add darker shading with your pencil or the 9B Crayon, which I did in this picture of his coat lapels & T-shirt. On the left side (facing you), I pressed lightly. On the right side, I pressed harder. Now you can press a little harder with your No. 2 pencil, but not to the point of creasing your paper and it will be grayish, not black. The dark parts of his hair, eyebrows, lashes, pupils sides of mouth, lower chin, and jacket areas go over to darken and keep referencing your picture.
