Time freeze finished! or not.

Today in class, after many re shoots and stressful editing, i have finally finished the time freeze effect for my film. However shortly after completing the scene my teacher advised me to redo one of the masks for the scene as when the killer freezes it looks like it could be a natural position. The effect will hopefully be wrapped up by tomorrow and all that will be left to do is combine the two half's of the film and fully render it!
