I recently made the entire set of dragon priest masks from the game, so I decided to step it up a notch.
Still cardboard and air drying clay on top and a massive amount of cheap superglue for strength.
The horns, so I don't waste a couple of packs of clay on those alone, I made out of a cardboard frame which I then filled with boiled paper, which resulted in a paper pulp paste. great filler material and it's pretty strong in the end.
Here;s some build pics and the end result as well (ignore the stencil in the sketching pics please) :
