The Gorax! Very stoked they updated this model as his animus makes him practically an auto-include in all of my lists, such an aggro man-beast!
Spot varnish used on his eyes and mouth.
(Spot varnish is my nickname for using a gloss varnish in certain areas on a model I would consider wet or glowing maybe, this comes from graphic design and printing when you use a gloss spot varnish on a print)
