I hate to say, but Right now is have to say indefinite. Ill break down exactly what's been going on.
Ive been dealt some personal obligations that consume a chunk of my available working time. also, I've recently had to move into a small apartment and don't have the proper facilities to cast safely or efficiently. Aside from that I've had trouble addressing the mold for the mask. For my part 6 I slush cast the mask, but that technique is time consuming and not always successful. I've also tried vacu forming but this method proved difficult as well. So really it's the mask and casting that's keeping this from happening. I can finish the head sculpt and mask I would just need a skilled mold maker/ caster to produce them.
I appreciate all the interest in the project, and I really want to make this happen, but I'm just not sure when it will.
