More expressive facial animations for survivors

This is something the game definitely needs in my opinion, the survivors all lack "expression" by that I mean pain sure you hear them scream but you don't see it on their face when you get hooked you should be able to see the pain on their face when you get stabbed you should be able to see the pain but instead you always have the same facial expression on all of the survivors, which is bad on people like Ace and Ash because even when getting hooked they have a weird grin, like they're smiling and screaming at the same time. it's more off-putting than anything some survivors are fine like Jeff but there is still room for improvement.
