Give the men the booty shorts and the ladies the pants? lol
As for the art I do feel bit of a difference, perhaps they can greatly embellish the "af2"? Concept art is generally free from restrictions in game so that tends to happen (I /love/ the Au Ra concept art and would have race changed if it was that lol), but yeah I like the concept art more but I imagine they could still make it later too. It's a good general AF (the render), but the concept art is nice and perhaps it can be the next tier still.
