You will need
- a sheet of paper, pencils, eraser, plaster head.
Prepare a work sheet paper, pencils of different softness, eraser. Install a plaster head on the surface, and the illumination source (or limit yourself to only a General illumination of the room, where you will work) so that the front part was lit. Set composite head position on the sheet. It is desirable that the top of the gure there is enough space ("air") and in the face, if you don't paint a full face.
Make a light sketch of the head with the neck. Mark edge - the place where the front surface passes into side. The lateral surface can slightly stroke. Refine ratio, the ratio of the cranial and facial parts. More accurately draw the location of the middle vertical lines, eye lines, nose, mouth. Mark the main parts.
Continue the analysis of shape. Or rather the build of the surfaces of the cheekbones, nose, lips, eye sockets, and so on. This is useful in order to properly apply the shadow to understand the structure of the head. At this stage, a light shading indicate the main shade. You should not work out some details more accurately, but still not get carried away. Your drawing should be drawn equally in all parts. Check the proportions of the head, using pencil.
Then continue to clarify and work out the nose shape, chin, nose, eyelids, ears and other. Strengthen the shadows, lay the penumbra. And "smooth" forms, refer to nature, to avoid the sketchyness in the drawing. To highlight your face - space in front of it gently stroking. Check the tonal unity of the picture, that was not too black spots and sharp corners.
When the figure heads are important not so much the amount of work and practice, how much precision work, accurate transmission, understanding the structure of the head and its parts. It is useful to perform the same figure has not from nature, but from memory on the smaller sheet format. It is also useful to perform the same head, but with a different angle. All this work helps to master the techniques of portrait drawing.
