This is the completed version of the pure 3D shot008:
vanishing Point of the elevator is totally different from the buidings' which will make the scene never looks right. And the Burj Dubai in the left bottom increased the burden of the whole scene again, it's unnecessary and destroyed the depth.
The matte painting version of shot008:
I havn't modofied the colours a lot of the walls in the concept art stage, I guided the comp team modified the colours and added several warm lights out of the windows in the comp stage.
Here is the final comp result, the matte painting I created has been used directly in the final movie .
This shot is for the second part that people could recognise that the character is falling down, so or the depressive and sad feeling we discussed to make the scene darker and bluer.
