These four are the main characters for a Game Cube game: Mystic Heroes. I'm in a group/club for it on DeviantArt: LegionOfMysticHeros. This and the other Mystic Heroes picture have been drawn just for my club, but I thought I'd share it with you all, too.
Left to right: Shiga, someone who's supposed to be Tai, Naja, and Lani. They usually wear chinese garb, but here they wear casual, modern days clothing.
