Going for a lowercase 'ork' or Fighting Uruk-Hai look with him, while maintaining the traditional Blood Axes characteristics.
 

(Tolkien never specified the exact skin color of the orc-men, though it must be noted they were racialized in ways that are understandably uncomfortable and implicit. But, artists took time to catch on to this in terms of appearance. It was Jackson making them all big Maori guys that established the image.)
 

You might notice the armor is Castellan Green. I went back and forth between that and a metallic or red. But ultimately, I decided on the drab green for maximum 'Blood Axe' effect.

Skin recipe is Waagh Flesh. I'd have to look to see what highlight I used.
 

His shirt is TTC Boar Hide, his belt and boots are Dryad Bark, his glove (which I didn't notice was fingerless until I painted it) is Rhinox Hide.
