Character design sketches for a project, all are different designs of the same character: a game warden who leads the player through the game. He is older and wiser than the player, and he is very mysterious.
Final character not posted. Each sketch was about 40 min-1 hr.
I would look at more refs for older and "wiser" looking people, these look more like fit, young security guards rather than someone the player would look to for guidance. Unless the player is 12, which is a possibility, as you didn't specify.
