This is from my current comission, and since this is halloween time i thought it'll be cool to release it so anyone can benefit from it. You can find the pepakura file at [link] , and the original skull model at [link]
Skulls are useful for cosplay, and this is so versatile that you can choose to build it for a mask by ignoring the Nape, or use it as a prop by ignoring the jaw.
WARNING: although it's anatomically right, since the eyes are deformed don't use it for a science project.
UPDATE: This is part of Guilty Gears' Dizzy costume, check it out at [link]
Enjoy it and pass the tip to your classmates.
Enjoy it as a cosplay, i happened to have the very same idea a few time ago.
really well done
