Camera Work
-execllent
-disorientating when needed to be,
-Shot distances appropriate to give disorientating feel
-variety of shots effectiveley placed for earie feel to film.
-Location shots good for setting the environment

Sound
-Sound could be made more relevant to whats happening, sounds a bit thrown in in places
-Personally would make the sound more atmospheric then synthetics

Mise en scene
-Good use of props the head bag was good for not suffocating their actor tho giving the appearance of distress

Editing
-variety transitions
blur filters and quick transitions effective at creating disorientation feel.
fade transitions create confusion then small window of realisation of new scene
