Here is another concept I'm tinkering with. there is still some more detailing that Id like to add but I think this gets the Idea across.
Afable, it's good work, continue on it, push it further. I feel the earpieces are a bit 1950's, maybe experiment with less "venting" and more "swooping"
The original concept was kinda open top but Im not sure how I feel about it, dosent really make sense, protect the jaw but not your brain pan. Im probably going to close the whole thing up, hard top or soft top is the question. The ear is a bit retro aswell, a rework may be in order.
id solidify the ear or make it larger bits, at distance itll just be ailiased? also how about some wires going tonto the skull>?
