This is a fig I've been waiting to do for some time. To get the flat skin tone I went for a Derivan mid grey and shaded it down with green and highlighted up with a flesh tone.
This one will be used as a stand in Varghulf, so I had to putty over the chaos symbols cut into his flesh, and add some extra fur and the skulls to tie it into the Dire Wolves that are being added to the army.
I kept the skin tones as muted as possible so the bloody mouth and glowing eyes really stand out (I wanted all the focus to be on the 'business end'). For this same reason I kept the fur and claws close to the skin tine too.
