What are considered to be the most important elements of storytelling in a short film - Skillful editing

Without skilful editing, the action would not flow as well, and the verisimilitude of the film would be broken, causing the audience to be distanced from what is going on. Additionally, good editing can change the pace of the film and the mood, as shown in The cat with hands, directed by Robert Morgan, using good editing skills to create a unnerving sensation for the audience.
