Basically, we enjoyed filming it! All thanks to the Metro, who provided the storyline for us!
I believe that there was very little that we could've done to improve the piece, the shots worked together in a uninterrupted motion. The acting of my crew was really effective, they really played to their roles. I didn't think we needed a soundtrack, as the dialogue was in contribution to heightening the tension, the gun shot sound clip was all that was required from the 'Sound' aspect of things.
Apart from that, it went really well!
