not really. it does a little, but this was a first-time-fursuit attempt so i wasnt too keen on attempting the articulated jaw just yet :3 i am going to have to re-do a few parts of the mask at some point though (the horns arent quite right) and when i decide to do that i might alter it so it can have a free-moving jaw. it does move some though, and if i open my mouth really wide, the jaw on the mask does open (that's why you can see it open to bite the snowball in my current icon) :3
