Greenscreeing isn't just a matter of throwing a character on a background. There are a lot of elements to take into consideration. Garbage matte, unwanted shadows in the greenscreen, reflections and added elements. Whilst unfinished, this scene makes good use of the mask tool to mask out the unwanted elements and t create fake shadows on the floor to add realism to the scene. Also the background and foreground are edited with an RGB curb to create a night time look
