i think at what some here are recalling to be "red eyes" , are just the lenses of their masks.
All u can see is something shiny, and some are thinking there to be red eyes they are seeing, quite funny i must say.
I am 6 foot 4 myself.
If i would place my wolf mask in front of my face, and i imagine me using 1 of those "buffed fat suits" like some of those actors are wearing, it looks quite weird.
Cause to look this kinda "normal", u really shoud be like Kevin Peter Hall his height, to get rid of the view that the head looks way to big for its body.
Guess with camera's u can do a lot to make it looks differend, so the head doesnt look THAT big compared to its body, LETS HOPE!
But i still believe that u cant totally change that, instead of using, like i said before, actors with heights like Kevin Peter hall or Ian white.
Not actors that are 6 foot 5 +.
Or use helmets / head that are smaller to make it look better on the body? might be a better option
