looks way better now, didn't like the weapons in the first concept, but that is a lot better.

About the book you designed, some dota lore for you. There is a demon language, but Shadow Shaman doesn't use it. He however much like Witch Doctor uses some weird language Examples being:
  • Moto Keyeyanna yaya, toyka yameh.
  • Neia teia an da ka!
Maybe incoperate that on the book cover instead of the demon head? Or you could hint at his story:
Born in the Bleeding Hills, Rhasta was just a starving youngling when picked up by a travelling con-man. For two pins of copper, the old con-man would tell your fortune. For three, he’d castrate your pig, for five, he’d circumcise your sons. For a good meal, he’d don his shaman garb, read from his ancient books, and lay a curse upon your enemies. His strange new youngling, part hill trowle, part…something else, worked as assistant and lent an air of the exotic to the con-man’s trade.

Always one step ahead of cheated customers, one town ahead of a pursuing patronage, the two trekked across the blighted lands until one day the con-man realized that the little youngling could actually do what he only pretended at. His ward had a gift—a gift that customers valued. And so the youngling Rhasta was thrust before the crowds, and the trade-name Shadow Shaman was born. The two continued from town to town, conjuring for money as Shadow Shaman’s reputation grew. Eventually, the pair’s duplicitous past caught up with them, and they were ambushed by a mob of swindled ex-clients. The con-man was slain, and for the first time, Rhasta used his powers for darkness, massacring the attackers. He buried his beloved master, and now uses his powers to destroy any who would seek to do him harm.

So a refrence to the con-man or just some coins on the cover, because they tricked people and the short story on what the con-man did when you gave him one/three/... coins?

Yeah I love small details in games ;)
