Another Thriller Idea - '17 and Gone'

This idea is about a youth in London who is heavily involved in gangs, drugs and violence. 

The overall plot is about how he is the key to his own downfall. The film will show him and his life over a few days and how he gets into 'beef' with someone else, who in the end kills him. The main character doesn't have any close family.

In the opening two minutes I would have shots taken from high and low angles of the main character walking around the estates in the night. There would be non-diegetic music playing over the top of the sequence with the titles rolling over it. For continuity editing I would make sure I follow simple rules with the camera like the white balance, the 180 degree rule etc.
