The section is dedicated to portraits - commissioned, educational and "for the soul".
Self-portrait is the best opportunity to study the structure and facial expressions, in addition to painting from life of other people. That's why I have a lot of them.
I often draw my students or friends, because you catch character and similarity better if you have a personal knowledge. I have placed portraits of animals with a clear conscience in the same section - after all, their facial expressions are as vivid and characteristic as those of humans.
