Thanks dude! When you finish making a character with it share the link in the comments so I can see. Also I just checked your gallery and I'm going to need some tips on making a mask of The Red Hood from Batman. Gonna need to film a fight scene.
Ok i actually am going to go crazy with it and do a race chart i've been having trouble freehanding. You'll get a link later. As for the mask... hmm depends what you want to make it out of. It looks like you may want to go resin on it but it'll be a challenge since it covers so much of the head. Anything else and you may risk suffocating in rubber. Check out my buddy Mike's gallery. He does resin fiber glass masks that will last for a long time but they ain't cheap. At least cjeck it out to get an idea. If you need more tips send me a note.
I have heard of resin but I had no idea what it was. I have read about people making a Pepakura paper craft mask then applying resin on it. I'll be sure to send you a note when I finish my current projects. Thanks for the tips!
Resin is essentially liquid plastic... but can be many things different types of things have been used as resin... blah blah blah... mummies have resin on them... blah blah blah... nowadays it's usually a multipart liquid plastic that uses a chemical reaction (usually endothermic) to harden them in to solid plastic when mixed (quickly and thoroughly). There... your science and slight history lesson for the day 
Helpful indeed! I have also heard of applying Bondo on the outer shell of a mask then sanding it until it reaches smoothness.
haven't seen that for masks but I have seen auto body filler used in customizing transformers.
