Premiere pro day to night

[thecrock]

Hi guys, a question.
I have a short scene that I need to turn to night.
I have been following some tutorials and get ok results. I reduce saturation and reduce reds and boost blue a little.
I need to make a mask at a window in order to darken it, can any wise member tell me how this is done?


Here is the scene without correction:
