Kingdom Death Gorm
The ugliest quarry in Kingdom Death: Monster, imo. I got this expansion almost purely for game mechanics (gear/cards) and reluctantly painted him because... ewww... But I actually rather enjoyed painting him.
Most of the contrast is up front because I wanted a dry/thick skinned look for his body as it's kind of like an Elephant or Rhino. But I enjoyed playing with skin color variations on his body as well as his face.
This was also the first time I tried any kind of subtle mottling. I thought he was gross enough and didn't plan on doing any veins, but I screwed up some of my glazing and cut that ugly coffee stain effect... so I did some mottling to cover up my sins.
