I am assuming the Ogre Hero is Cho'Gall...
Someone already made the model...
Here's the link : Cho'Gall
I will try not to take too much time on this Zul'jin model...
Usually that will kill my interest if I take too long to make the model...
So please answer several details below for Zul'jin;
1) What weapon will it use? (WoW version uses 'Fist of the Deity')
2) What is the model's body build? (Shadowhunter thin, Forest troll bulky, etc)
3) The model's attire/clothing? (WoW version or something else)
