Saturation and exposure changes

 I increased the exposure of the lighter areas slightly whilst lowering it for the shadows so that the shoes stood out more.

 I increased the saturation of shadows so the red bus became more red so that it stood out and becomes more iconic showing that it is London.

I increased the saturation of the buildings in the establishing shots to give a lighter, more upbeat mood for the beginning of the clip. 

I added a red tint to the prostitution scene to show lust.
