thanks, I was going for the Batman Beyond color scheme, going to add some yellows, silvers, and reds in there too, time permitting.
as for the head detaching....I was thinking Id get in contact with the guys who did the original "The Thing" Special Fx, they seem to be pretty good at that sort of stuff lol.

I love foam, I tried Peps, did a few star wars helmets and a few anime characters with them but the are soooo tedious and time consuming with the cut cut cut,glue glue glue. Foam is the one thing my town had a ready supply of, and the stuff is great, mix it with contact cement and it will never break on you, the stuff is almost as good as gold.
