I can pretty much sum up why city hunters mask looks goofy. And this is also why I think it wont be changed
First off its curving up makes the amount of mandibles shown terrible looking. It really does need a small filling under to look better.
But beyond that, its about size. Consider that the mask used for city hunter in the film didnt have to account for predators actual “face” because it was removed when in use other than for the reveal scene most likely. So its already gotta be changed to actually account for preds face/head sizes.
But beyond that, to some extent illfonic has to keep consistency between all pred classes and their heads dimensions, because all pred masks can be swapped and vice versa. So even if they managed to make it look like the OG and still fit on city hunter, it almost certainly would break on other preds faces.
Tbh, while there is probably room for a bit of improve ment, its never gonna be like the og because the og is just so out of proportion.
(Also if you look at most city hunter action figures you can see that they look exactly like the in game mask… Because they also have to account for city hunters actual face.)
