I envy your skill. I hope that if I dedicate twice as many hours I may get a result that is just halfway to your level of sculpting.
The details are amazing, the smoothness, the accuracy... Just wow!
actually yes, helmets can be and are often referred to as buckets due to their obvious shell shape that holds things like your head. Buckets are shells that hold things as are helmets. You seeing what I'm saying?
Just a recommendation but you should get a screwed up HJC visor off someone and make the edges round it fit that, then do your molds. B/c everyone that shells out to buy a molded helm uses an HJC not a Westy.
