Current film opening feedback

So far we have done about half of our 2 minute film opening and the criticism we got was good for our project because we have taken this on board and have decided to add different shots and to create more suspense. The criticism we got was that:

1. The audience did not feel sorry for the female victim because we do not really see her much in the opening. 
2. The wrench is not clear enough so we have decided to have a close up on that to make sure the audience knows what it is.
3. The cut between the mans smile turn to a frown and the woman being dragged away needs to be more clear why that is happening so we are having a shot of Dave swinging the wrench at her.
4. Dave's smile is not clear the audience thought it was Elizabeth smiling and then frowning therefor to make it clear we will change the shot completely to Elizabeth's smile go to a frown so we will be showing the reaction instead of the killers face.

Due to these comments we are filming on the 16/01/12 to get the film finished hopefully before the end of the week.
