Chun Li and Cammy minifig, back view
Want a better look at the hairpieces? Here you go.
Chun Li's ox horns and ribbons are just Milliput. Cammy's hairpiece are the pigtails from the Series 7 minifig's Viking Woman, hacked off and glued onto a beret which was painted. I did a slightly sloppy job of masking off Cammy's braids before painting.
