Horror Film Sequence

In groups, we were given the task to produce a film sequence of 10 shots in the genre of horror. Our group had the idea to use one female character as our visual. We shot her in an establishing shot of a comfortable, well lit environment. We then changed the mood by cutting out the lighting and filming the character frantically panicking. We also chose to use diegetic sound as our 'killer' as we felt this caused more suspense to the audience as they would never know where the killer was.
      I feel we portrayed the horror genre well in our short sequence and captured panic and fear in the characters' eyes. I feel that to improve we could have introduced some non diegetic sound to increase the amount of tension and suspense that the audience may feel.  I also feel our lighting let us down as although we aimed to use low key lighting to help with the emotion portrayed in the sequence, the outcome of our shots were underexposed and we lost the effect we wanted to achieve.
