I think there's two main things that would help. Number one is that most of the ones used are very recognizable from other franchises and can kind of take you out of the fiction. The other thing is the lack of supporting sounds, they feel unnatural because we go from nothing but music to just the sound by itself. So ambient wind, the growl of the monster maybe a faint heartbeat or heavy breathing could turn the sound effects from a standalone element to a supporting item in an immersive soundscape.
