My shot makes him look so huge... XD They're big, but not too much bigger than a Galka really. That shot makes them look Gigas-sized. o.O
As for his carrying a great sword in one hand... just about every type of mob that carries great swords carries them in one hand; Quadavs, Goblins, etc... The only ones that don't are shadows, really.
Useing a heavy weapon in a single hand, could it have smething to do with the fact that they might just have the brawn to do it? Then again, its alot more work to make them put both hands on the sword for an model like these.
