Foot image
Many of the tips for helping to draw hands apply to the legs, although you will have to use photographs, statues or friends’ help as models, because drawing your own leg is much harder than a hand!
Proportions
In these figures you can see the widest part of the foot; its maximum length is approximately two and a half times greater than its maximum width. Note that the toes are less similar than the toes. Remember that the rise of the foot is a small notch on the sole and that all the tips of the toes of the standing foot touch the ground. If you want to draw a pair of legs on the side, do not forget that the ankle on the outside of the nearest leg will be slightly lower than the ankle on the inside of the other, distant leg.
Foot contour
As with the arm, look at the leg as a whole in a basic geometric shape — it looks like a dull wedge suspended from an ankle; fingers are attached to this wedge. Ankle - an oval protruding from the lower part of the leg.
Traffic
When walking, the weight of the body goes first to the heel, and when the fingers are compressed, it moves to lift the arch of the foot. Finally, before the foot comes off the ground, most of the weight falls on the bent toes, and vertically above them is the rise of the foot.
When people walk or run, their legs function in pairs and the weight of the body moves from one to the other. Notice how the leg muscles tighten and relax along with the removal of body weight. Pay attention to those cases when, when moving, both legs touch the ground at the same time, and look at their shape. In a running person, only one foot is always in contact with the ground.
If you look down when walking, you will see that your legs are facing slightly outward, and not in the direction of movement.
Surface texture
When drawing people, one has to meet with a variety of textures - clothes, hair, skin, and so on, and each of them, in turn, also differs in the variety of its own texture. For example, hair may be curly or straight, skin wrinkled or smooth. You must portray all this accurately and correctly in order to bring realism to your work. The real texture found in life is presented on paper as a reproduced texture.
Reproduced texture
Various textures can be transmitted using a line diagram, as well as chiaroscuro, which distinguishes wrinkles and contours. You can also use the quality of your work materials. So, you can identify the surface texture of cartridge paper by rubbing its surface with a soft pencil. Most of the texture in the portrait of the fisherman (opposite) is conveyed in this way. And its other part is revealed through the use of light spots and shadows.
