If you're a fan of Tera, the new MMO on the block, you might want to take a look at this gallery, because it features the work of Kim Hyeong Seung, a concept artist who has worked on the game.
Almost everything here is from the game, with the exception of the obvious. Like the giant mech.
You can see more of Kim's work at his personal site.
