[REQUEST] What could I do better in my CS?

For scripted events, in my opinion, you should always focus on making them realistic.
If the place you're walking around in is half destroyed, you could make a scripted scene where some debris is falling down and scares the player.

If there, according to the story, is hidden a body in a closet, make it fall out and scare the player.
