An artist exercises his technique, much an athlete his body. So here are more tips on freehand drawing. Stroking, shading, highlighting gives realism to a picture. Light falls on the ball to produce shadows and reflective light. Light also makes smooth surfaces like a chrome cylinder shine. Light brings out the texture and shine in hair. Practice by making these shapes and shade them in. Hold your pencil 45 degrees from the paper, hold it like you are rubbing or wiping something and stroke. Try drawing an eye-like shape that matches the hair and stroke with your pencil. Start dark from the corner tip and lighten off near the middle. Work from the other corner of the eye-like hair shape, stroking from that opposite corner toward the center where the light area is in the middle. Leave the middle white. To shade a huge area like Stefan's face, without making sharp long lines that overlap, lightly draw in small circular motions with a sharpened No.2HB or 4B. Then blend with a tissue, queue-tip, blending tortillion or stump.
