The new Seraphim helmet sculpt is a piece i built to fit my own head and face shape. However i designed the back so that the whole area could be dremeled/cut off and attached with elastic or shaved down in stages without the need for elastic. The back section is cast thinner to make this a little easier. It can be thickened with lightweight epoxy or other methods. Or you can just sculpt your own back design or customize the back piece sculpt- maybe even get rid of the back and add a cool fabric techno dreadfalls look using lightweight flexible hoses, etc!
