Short film analysis-Tom

This is a short film in which I will analyse. It is about a strict school that teaches its pupils that the wrong answer is the correct one. One pupil then disagrees and he has to face the consequences. There is an almost 'faded' effect in the shot which distorts the picture to show the film has a dark theme to it. 
The film uses a lot of close-up shots to show main points of focus. For example, we see a close-up shot of a blackboard early in the film. This shows the blackboard has some significance later on. 
Also, we see a dolly-in zoom shot which zooms in on the speaker in which the headmaster is speaking through. This, again, showing that the speaker is relevant to the storyline. 
Close-up shots are used throughout to show emotion on the characters faces. 
Shot/reverse shot is also used in the film, cutting between the teacher and the pupil during their conversation. 
Mise en scene consists of the props used, such as the blackboard, board rubber, chalk etc.
Costumes included the uniform of the pupils and the teacher who was wearing a suit, giving him a higher status than the pupils as they are all dressed the same and he isn't. 
An extreme close-up font is seen near the end when the pupil who answers the question 'incorrectly', he is then shot by the higher pupils. Although they aren't technically holding guns as they are invisible. In the extreme close-up we see the blackboard with blood then being sprayed onto it. As if he'd been shot. 
Low angle shots are used, looking up. This is filmed from the pupils perspective and shows the teacher (and higher pupils, towards the end) standing above them. This shows he has more power than the pupils. And therefore most fear him. 
At the end, we then see another pupil refusing and writes the correct answer in his book. This is filmed using a medium/close-up shot.
