I’d like some tips on blocking out the main shapes of faces for portraits
For proper head construction, first draw a vertical line, which sets the centre of the face. Then determine the location of the major parts of the face: eyes, nose, lips and ears. They should follow the formula that a face is divided into three equal parts in height, bisecting the line of the forehead, eyebrows and nose. The eyes should be properly positioned relative to each other, with the distance between them being the width of an eye.
From the inner edges of the eyes draw vertical lines. The intersection with the line of the nose gives you the width of the nose. The nose is divided into three sectors in the form of a trapezoid. The mouth is determined by vertical lines, drawn from the edge of the irises. The line of the mouth extends somewhere in the lower face but sometimes higher, depending on the nature of the character you’re drawing.
The most pronounced planes are the cheekbones, forehead and nose. The forehead is determined by three main planes that start from the beginning of the eyebrows and the acute angle of the eyebrows. To define the cheekbones, draw a line from the top edge of the ears to the ends of the mouth. Determine the border and the proportions of the upper and lower lips, and don’t forget the groove between the nose and upper lip. Of course, you need to remember that people are different, and each character requires an individual approach.
This girl has coarse facial features. She has wide cheekbones, a big chin, a large nose and full lips. She looks a little like a young man.
This woman has classic feminine facial features. She has the same proportions as the figure pictured above, but the result is a different character.
