The models on the first post look great!
I can't say the same for Kargath Bladefist... he's... forced, if you get what I mean. Few things about him: the beard is bad (low-res?), it would be best done like Thrall's. The glow makes it impossible for the model to be used as a unit (well, not really, but it always looks bad, doesn't it?). If you could remove it and add a decay animation, you would open a lot of other uses for the model. And what's that huge brown thing behind his head? A coat? If yes, then you should perhaps lower it's size, it looks kinda ridiculous.
Good work on the Warsong Grunt. So you're really creating a grunt for EVERY clan?
