Feet
The feet are sometimes the hardest parts to draw, since they are most often
viewed at a foreshortened angle.
The best way to draw feet is to block them in lightly using simple geometric
shapes and then adding detail.
Note the tendons in the feet and the creases. The outside of the ankle should
protrude more than the inside.
Again, observe your feet in different perspectives to get an idea of how they
are formed.
Shading is also important in creating a realistic looking foot.
