Trolls of Middle Earth - Lord of the Rings

This is intended to create the various trolls from the Lord of the Rings franchise. Training images were taken from both movies and games.

They types looks fairly similar, but there is still a little distinguishability. These are the ones I've tagged:

Cave troll

Mountain troll - visually similar to cave troll

Snow Troll - most distinct. Usually have blue skin and long tusks.

Olog-Hai - The most intelligent, have a more humanoid face and usually wear armor.
