sound
when Mercedes is singing the lullaby the scene gives off an innocent feeling Although this transitions into Mercedes doing something sketchy. as the scene transitions so does the music going from a simple lullaby in a major tone to some ominous minor music
mise en scene
the use of different types of foods on the table tell us a lot about the scene. in the scene with the pale man the room would be fairly hot and so the use of fresh bright fruit is used to make Ophelia want to disobey orders
in the scene with the Capitan in the real world. the food looks more dull and homey giving the impression that this is the real world
cinematography
the use of high and low angle shots shows a clear level of who’s in charge. as Capitan Vidal ises low angle shots it gives the impression that he is looking down at the camera
editing: the use of the wipe makes the 2 scenes seem connected and make it clear to the viewers this is all in the same world.
