What I find interesting is the fact none of the giant's faces are shown in game. They're all wearing wood and chain coverings. It's as if they're trying to hide the mark of their species...

Smough could be a giant for all we know. He's berzerk and somewhat crazed (the way he smashes Ornstein for his soul). Maybe the armor that he wears is an attempt to convince his enemies that he's not a giant, and to clarify, I never ever thought that under his mask would be a gaping hole.
