art director is the person who makes sure the game all fits in together and keep the overall theme of the game without makes thinks look mismatched so that game is a believable world the art director will check all the other artist work an all the work that the artist do goes through the director for feedback and critt will also be in charge of all the different artist that work on the game and the the specialist which is what im trying to work towards at the moment as well as been a jack of all trades working hard one to get into the industry with witch for me is character design as a 3d artist and or concept artist but they'd also have to look over the vehicle artist, characters , environments , weapon an vfx artist.
