Hi there, sorry for the late reply or silence...
After looking at the model again, I'm thinking of making some minor overhaul of the model (I'm not satisfied with my work on this model. It doesn't look as bulky as a common Forest Troll from my view).
I've gain some experience from a recent work, and wanted to apply those knowledge on this Zul'jin project if you're not in a hurry for the model. If you urgently needed this model, let me know...
