How is it different from the original sample?

My original idea was to have four character who were caring on with their routine when they receive  a black box which changes their world upside down. Plot wise the story is same, the only thing that is different is firstly the number of characters. My original plan was to show the scream first and then show them in their daily routine. but now that has changed.

 The beginning of the opening sequence start with showing the characters receiving the black box out of the blue which was then followed by scene where all the three characters enter the three doors at the exact same time which was followed by a scream sound and then a hand is shown striking or making cross on the character's photographs. 

This was again modified as in the final the scene where the three characters are entering the three doors was pretty odd and random so I changed that to having their picture on the doors which would give a better understanding of who is behind what door. 

I think by the end of the process my original idea has changed as I experimented different ways of adding more meaning to the opening sequence.
