The original environment was much lighter and less populated with interesting little nooks and crannies. To help the mood of the story, which was intended as a sort of existential psychological thriller about a mother coping with the effects of drug abuse and the loss of her daughter, we completely reworked the lighting as seen in the above images.  I personally prefer this environment to the other version, as the overall lighting is much more cohesive. The decision to make the change to the other version was a team decision.
