Step 1: Draw a circle to locate the head top, then draw the axes to determine the direction of the face. Depending on the face's view, the curve and direction of the axes will be changed accordingly. So please imagine the angle of view before drawing the axes UwU
Step 2: Draw the contour of the face. Note that the top circle's diameter is usually equal 3/4 of the face's height.
Step 3: Draw eyes, nose and mouth for the character. Girls often have big eyes, small nose and mouth, while boys usually have higher nose.
Step 4: Draw the hair and some other details. Note that the ears should be on the same height to the eyes, you can base on the horizontal axis to identify, to avoid deviation UwU.
Step 5: Hide the outline layer (for the digi), or simply erase the sketch after lining (for the tradi). Then we have a beautiful face already:>
