The bright red plastic ear muffs kind of take away from all the detail that went into the rest of it. If the point is hearing protection, I bet earplugs would offer enough protection. And if those are for communication, they could have gone with something like these
retro WWII style headsets.
Sure, red plastic ear muffs are very practical, and I'm a sucker for practical, but nothing else in that picture is practical, so they seem out of place.
Looks like fun though.
