I can finally scan my images (Scanner at my new school). Unfortunately I had only a sketch to test it with. The idea is that it´s a helmet that can be taken completely apart and modulated with different pieces. The top two have similarities just to show that they are essentially the same helmet. The bottom on is absolutely modified for use by high altitude pilots. I apologize that A. I took so long and B. I could only get a very unimpressive sketch.
