Shot Composition Task Video Evaluation

The aim was simple, create a short movie which consisted of deeper meanings and a variety of shot composition techniques. My movie consisted of two males, one following the other silently. The video will be shortly uploaded to YouTube where I will be showing it to other students who do not study media and ask them for their opinion and ask them what I can improve on. I already know of two things that I wish to change:
Firstly the location. The layout of props was perfect however there were a few small things which ruined the overall feel of it. For example at the start we can see a laminated poster on the far left wall. It may not be of any large importance to a viewer but i think it ruins the shot. The reflection is gives off is nasty and I think it makes the shot look cheap and poorly made. The second thing I would like to change is the bgm (background Music). Yes it seems to fit but at the end it reaches it climax and begins to sound like a fight is about to happen however this is not what I need. Although this bugs me, I do know of a solution and that is just to slightly change what part of the audio the clip plays. The audio I had in mind for that final shot was in the song I had used but I didn't have time to mess with it so that the specific part of the audio would play but that is easy to fix.
Overall I am pleased with my work, especially the colours. I changed the saturation of all the colours within the frame so that it looks cold which I personally think looks great. I did have a fellow media student review the footage and she did spot one of the smallest details which has a very deep meaning. At the middle of the clip we see the male who is being followed walking down a dark corridor towards "the light at the end of the tunnel". The male who is following goes through a door and next appears in front of the other male, blocking him from reaching the light at the end. It was also spotted that the male following was wearing all black which represents the darkness which is stopping the other male from reaching the light. feel free to check the video for yourself:
