When me and my partner showed our class mates the animation of our film we got a series of different reactions.
Our first problem was that our animation is incomplete, so we wasn't able to give the desired effect, there was some sound effects that was missing, due to time but also the fact that we was unsure of how to make the sounds, for example a heartbeating slowly and then increasing, and also the wind blowing process was a problem because it didn't sound very realistic and didn't match the action in our shots. 

Another comment we was given was that it wasn't long enough, and that it didn't seem scary, this could either be because we hadn't finished adding the sound effects so the tension wasn't felt.
We was given an idea that tension should be added, but we believe that the first two minutes of the film doesn't necessarily need to be scary at all, but we will be dropping little hints into the plot, so when the friends are walking down the alleyway, in the background we will have the sound of the little girl humming in the background.
