A lot of them - Dire Tiger, Greater Basilisk, Giant Eagle in particular - seem to have been shot from rather unflattering angles, which is a bit odd. Those three looked much better in the spoiler pics from a while ago.
Agree this set is all about the uncommons and commons - shadow, babau, carnage demon, greater barghest (typo in the gallery - it's really an uncommon), cerebrilith, brass golem, earth mephit, the gnoll, the kuo-toas, eagle, medusa, chaos beast and carrion crawler (despite dumb saddle thing) are all great. The three mounted rares, the three unique rares, the Shadow Dragon, and a few of the Medium rares like the Shadowbane Inquisitor and Exarch of Tyranny are distinctly underwhelming, but should be usable as trade fodder if I'm unlucky enough to get them - and since I'd like multiple Noble Salamanders, Berserk Flesh Golems, Dread Wraiths, and Dire Tigers, I'll probably need it.
