“The purpose of this project was to create a portrait of a real man, to test my skills. The likeness was my main goal. First of all, I decided the subject of the portrait. I wanted a person with peculiar physical features and, in the end, I chose Benjamin Linus, my favorite character on Lost, played by Michael Emerson.”
