Ever hear of 'the thousand yard stare?"
Drama is for movies and actors; and only amateur warriors show their emotions. A trained or professional fighter/killer is emotionless; or at least keeps a tight reign on emotions. Certainly there will be no outward display. An emotional warrior is a dead warrior.

These guys are trained professional fighters... look at the expression on their face.. I dont see "the thousand yard stare"

Look at the guy on the left doing the punching... look at the veins on the head the shape of the mouth the lift on the eyebrows there is lot going on there and its not a cold stare.

Look at the guy on the right receiving the punch... look at the eyes, the open jaw... lots going on here.

I've seen exceptional renders that look like the scene below, only to have the poser characters
looking like they are constipated.
