Camera angles used in my opening

I have used a lot of mid angle shots in my peice, and also angles that hide the charecters face. For the basements shots, the angles are all mid shots, including half of the charecters body and also include the mise-en-scene. The pan shot used for the drag scene is used to emphasise the amount of time and the surroundings in the action.
In the opening shot, the angle is a high shot looking down on the charecter showing him as weak. The shot then zooms out to reveal the office around him, again encapturing the mise-en-scene.
The angle used when the mobile phone starts to ring increases the high drama and intensity of the shot, also framing the unknown caller flasing on the phone.
Most of the angles used are meant to be intimidating and personal to the charecters so the audience can get closer to the action, making it more gripping and realistic.
