Well as usual when I need to find photos of what I am talking about I can't.
Hal, that pic is of Thor not odin. What I was more thinking of was extant carvings, sculpture, drawings, paintings of Norse gods from medieval times. Then manufacture a face out of that style so that it might look like something a norse cheiftan might wear during a ceremony.
There are certain aspects to that period artwork that makes it LOOK like it was made back then. Things like straight lines when drawing a beard, large football shaped eyes with no pupils, flat triangularish shaped noses, The folds in a robe being very straight, etc.
Like I said before it would be simpiler to manufacture the face going by these guidelines BUT, I think you would end up with a truely fantastic fantasy helm heavily rooted in history. (something that while fantasy LOOKS like it could have been made back then)
Now, if you were looking more towards straight up fantasy and not trying to tie it in to history, modern comic book drawings of odin or Thor, loki, etc. would work just fine.
Just my .02 cents
