Half-Life Papercraft: Headcrab Zombie Mask

I consider this papercraft project something of a failed experiment, but I thought I would post it anyway just in case someone else might be able to do something with it. My original goal was to take a 3D model of a headcrab zombie from the Half-Life video game and turn the zombie's head into a full size hollow paper model that could be worn as a mask. Well, that was a nice idea, but after I did a test build it became apparent that the thing was a little too strangely shaped to work well as a mask. Still, someone else might be able to modify it to get it to work. For those unfamiliar with Half-Life, headcrabs are parasitic creatures that attach themselves to a human host's head eventually turning the host into a zombie. The faint skull image that appears on this papercraft model is presumably the host's skull showing through the headcrab's tightly stretched skin. Details of the template are as follows:
