I assume you're talking about the main barb pic at the beginning of the class writeup? I agree. When I first saw him, I noticed how weird his face was. And his hair. But the thing that really stands out in my mind is his man boob.
I decree that hence forth, he shall be known as Moob, Iconic Barbarian.
The Adroit Explorer and Turathi Highborn are both lacking art.
I really love the art for the Ancestral Incarnate, Shiere Knight (despite her face kind of seeming off to me), Invoker and Zealous Assassin.
Most of the 4e art is terrific. I recall a few wow moments just reading Dragon and Dungeon magazine. Every now and then there is some crazy exception....like that Barbarian. What in the world? He seems to suffer from gynecomastria (man boob), and just does not seem to be proportioned correctly at all.
However, that's the exception and not the rule. Overall, I've been very impressed by 4e art.
