Valkyrie is more of a statue, but the head still pivots. She started as a Harumika mannequin figure that was all white plastic with doll hair. I cut her into segments to alter the body proportions, then resembled her using screws and pop sticks. Then finalized it with Epoxy Sculpt, a full paint job, and added back the hair. A Xena, Barbie, and a few action figures which I don't remember were used for the accessories which were modified. Everything else was just junk jewelry and cheap craft stuff. The base was cut to fit and painted with a plaque added.
Some of you may find this useful: I do test sculpts with Play Doh to save on expensive Epoxy compounds. This gives me unlimited test time, and also reveals how much material is needed.
