He appears to be alert, as if looking at what's coming at him. More than looking, giving his foe the tranquil, yet deep stare of an individual whose first battle was against his own fear.
Very adequate for a paladin. He looks calm and wise. Yet not overloaded with holy lights and ridiculously shiny armors. Holiness can be shown in a subtle way too, and that way it also leaves room for other feelings to seep through.
In RPG's, Paladins are my preference. I kind of see them as the ideal hero. The kind of character that (when things look darkest) are a bright beacon of hope for their allies: Strong, brave, selfless, wise and faithful. The kind of character that is incorruptible, pure and pious, yet also has great humanity.
