Having fixed the height of features, draw in the curved line, starting under the eye, forming two onion shapes with a single line, carrying it round to the bone of the nose, around the wings of the nose in a sweeping curve to top of the chin. Space between the eyes is the width of an eye.
Across the wings of the nose is the width of an eye. A line dropped from the corners of the eyes will enclose the nose. The inner corner of the eye is slightly lower than the outer corner.
Front Neck.
Muscles of the neck are as follows
0 : Sterno-mastoid. S : Omo-hyoid. T: Sterno-hyoid. W: Trapezius. K: Thyroid cartilage. U: Hyoid bone.
The side outlines of the neck, which are bounded by the outer edge of the sterno-mastoid, start from the jaw-bone (about level with the mouth) with a slightly inward curve, then out and gently in again ; then spreading out to the collar-bone at a slightly greater width than the top.
Measurement from bridge of the nose to the chin is equivalent to that from pit of the neck to the chin.
Three-quarter View: Blocking (Plate 24).
Two elongated egg-shapes overlapping will suggest three-quarter view of head. Construction lines take upward or downward curve according to the movement of the head (C and D).
The middle line of the face must be placed three-quarter space over. The near side is so very slightly turned that the perspective will hardly be noticeable, though this must be indicated to a very slight degree by foreshortening features.
On the turning half C perspective will show to a much greater degree (see Plate 25).
The shaded space on Plate 24 is from the roots only, and has not allowed for overlapping strands of hair on the forehead and sides.
