A portrait is not a likeness. The moment an emotion or fact is transformed into a photograph it is no longer a fact but an opinion. There is no such thing as inaccuracy in a photograph. All photographs are accurate. None of them is the truth.
The best portraits are those in which there is a slight mixture of caricature.

Frankly, it's embarrassing to have a house filled with giant portraits of yourself.
Portraits are about revealing aspects of an individual.
