Neve. This Italian artist began in the streets and continues to bless walls with his super realistic style, but what attracts me most to his work is not what you see on the streets but what you see indoors. He uses a childhood favorite, the crayon, to do beautiful photo realistic pieces on things like cardboard or blackboard like with the 'Draco' piece above. His images are classically refined, inspired by figurative art with an emphasis on light (very Caravaggio-esque). It is hard to believe that all this emotion and suffering is achieved with just a crayon... it's an incredible talent.
