Now we draw the face on this curved surface.
There are a lot of instructions out there, but here is my simple method of practicing:
– First mark the top point of the forehead and the bottom point of the chin.
– Then find the center between the eyes, the lower part of the nose and the center of the lips. Mark them and connect them with a curved line.
Now we have the vertical alignment and placements.
– Measure the width of the eyes, mark the edges and connect them again with a curved line.
– Add a parallel line at the levels of mouth, nose and eyebrows.
Now you have the placement of the facial features and can draw them easily.
