1.  Sketch a horizontal line along the eye bases, and that line will be referred as "Eye Base Line".
   Using a measuring ruler or triangle ruler can be used to keep the eyes level in respect to the bottom edge of the paper (see #2 below)

2. Draw a vertical line between the eyes, and through the point of chin.

 The purpose of such lines is to help level the face so the face won't look too loopsided.
