I am embarking on my quest to master the Non Metallic Metal technique. Here is my first formula for simplifying the process. I call this color scheme 'Cold Steel'.
Basecoat with The Fang
Layer on Warpfiend Grey in a stylized fashion.
Cover about 50% of the axe with Administratum Grey.
A thin highlight of Screaming Skull finishes the effect. Deadly Axe, huh?
