Use the HB pencil for outlining the face. Eyes plays a vital role in any portrait. Start shading the eye balls first. Gradually shade the eyelids and then the eye brows. Move down towards the nose. Drawing the nose too high, or too low, or drawing one curve too big could completely disfigure the face. Shad the lips, leave some part of the lower lip unshaded.
