User blog comment:Brutal Templar/The Giants of Lordran could possibly be very close kin of the Giants of Dark Souls 2./@comment-16047389-20140404143842

There are more differences between the Giants of Lordran and Drangleic than just their faces. Proportionally, their bodies are vastly different. While the Giants of Lordran had bodies that just looked like oversized humans, the Giants that invaded Lordran had thick torsos, but extremely thin and long limbs.

And while we never do see Gough's face, we know he had eyes. His helmet had it's eye holes filled with resin to blind him. So it is likely that he had an actual face. Also, Gough actually had skin. If we look at the Giants of Drangleic, they are made mostly of what looks like bark. The Knights in Heide's Tower of Flame look closer to what Lordran's Giants looked like than the Drangleic Giants.
