the artist's rendering of 'Keyser Soze' as described by that dude who got burnt up seemed to depict Verbal Kint. however, VK claimed that KS changes his face all the time. plus (this is me lawyering) those depictions are often faulty as eyewitness identification is notoriously unreliable.
and i agree - most of what we know about KS came from VK and he was lying through the entire movie. so we don't really know.
