Shot idea and music for film

i had an idea today that i told my partner we could use and it is that we could have someone running through the woods and the camera would be placed tracking the characters feet with the leaves or mud on the floor and then for them to trip, this would show that the character is running for their lives, also to have a shot of the killer to be standing there and the shot to be on their shadow and then to see them produce the weapon that they are going to use to kill the character running this could be effective if we edit it right because we could make the audience jump the music would play a massive part in creating the suspense for both when the character is running the music will have to be fast paced and scary to emphasis the terror that the victim is going through and also to show how fast they are running. when the camera goes onto the killer character the music will have to be fast and daunting and then to suddenly come to an abrupt stop this could suggest to the audience that it is the end of victims life.
