Rembrandt, as in one of his selfportraits
Some portraits of different techniques. The ones from Game of Thrones actors and Dio are charcoal and pencil. The ones of Dave Brock and Snæbjörn Ragnarsson were made with graphite, turpentine and ink, the last on cardboard. The portrait of The White Buffalo is digital and made with Photoshop. The study of Rembrandt's self portrait was made with oil on Caballo paper.
