The updated version:
Details on the Bioshock 2 Big Sister Helmet.
Story was, I didn't really intend to make this costume until I came across an old-school world globe I found in the garbage of a school.
And from then on, the ideas kept flowing...
It does have breathing holes, various punctures / "bullet holes" punctured into the helmet, which are moreorless visible to the eye. XD
Helmet: World globe used as a base, spray painted the base, painted over it using acrylic paints and various markers, and then painted PVA/Wood glue over it to protect the surface (WITH FISHIES)
Lense: Lid of a round lunch container glued onto the helmet (using silicone), painted over it with acrylics and markers, bike light glued onto the back of the lense (lights up), with bolts glued onto the rims
Lenses: Bigger lense on top of the helmet is made from some "beer" goggles with a flashing light in the centre, the smaller lenses are hose connectors painted over and glued on (one of them has a goggle lense glued onto it and painted over with nail polish) Time it took to complete:
Uhhhh...5-7 months...? Would've been less time if I had all the pieces I needed all at once. XD
