I actually have no doubt that this could be an incredibly scary trail (for many reasons). If this is a single layer then it is a good start. More of this, more sight break up, more junk on different planes and eyelines.
I think this is standard haunted house stuff here, this is the norm or just below it. My assumption is that this haunt is actor driven, nothing wrong with that at all.Just add more things to be good distractions. And watch my videos, make some bodies, keep adding layers.
