For this Nob I wanted to create an ork that was the least "comic relief" I could.
In addition to a slight re-posing and modifications to the weapons, I also bulked up the body with some epoxy putty: add a blob to each existing muscle and smooth it in.
I also opened the jaw wider. This left only one tooth and a lip ring. Ol' one toof was born.
The boss pole also reflects this.
Then add a touch of blood from the last person that laughed.
