Here is an observation or food for though. There are two things that are always done. One is if you build a mech people always feel it needs a mini gun and if you build a soldier or figter you nead a verticle cut over the eye. He is a brawler isn't he. You could give him a scar on the bridge of the nose or running along the check bone or brow line were the bone cuts the skin as it is pinched. Just a though to be a bit deferent but still having that tough look. The modeling and texture do look really good. Techniqually this is done very well.
