Wow.
You created the next playable race, methinks! You imagined it with armor, a mount, and a uniquie appearance, all of which are the factors that go into the races.
The subject is fantastic; lots of detail and very creative. The background is superb, particularly the water. I like the "Wanted: Murky" poster on the turtle's back.
And no, Qou, that looks nothing like Zangarmarsh. Maybe Dustwallow Marsh or Feralas, at best.
