I can't seem to stop making these!!  I found the helmet in a charity shop .. but as it was rather big to go on the top of a chunky I took the saw to it and  placed the larger half at the top and the "face" bit on the back 

The sheilds are button/brads backed with leather, metal shimms or charm frames and then painted with alcohol inks.  A couple of barbecue sticks and some foil made the spears.  The rest is paper in various guises!!.
