The only pepakura file I know of is from PapercraftMuseum, a textured model ripped from SSBB. Not sure how much it helps, but some of the armor is in there and built separately from Zelda herself. The shoulders seem the only feasible ones though, sorry.
heh... you called me piggy... he he...
...and I guess I am a grammar nazi I found like 6 mistakes in spelling on my English test today.....yeahhhhh........
lmao I was just doing Lord Of The Flies so piggy came to mind
As for the build....still go for cardboard, if you are lacking ref. pic to actually build a "harness" look up Claymore. The anime has a similar piece you can use as a base
