Original OD&D had Balrogs, Hobbits, and Ents.That last dude looks like a rock and roll star. I think its difficult when you produce so much detail, such that you have to make them modest with a loin cloth, versus less detail leaving the viewer to use their imagination, e.g. the Balrog in LOTR.
One thing I never realized, Balor was the name used because they couldn't use Balrog.
