This scene is the climatic point of Amber's journey, embodying her frustration and helplessness. It needed to visualise forces out of Amber's control, i.e. Nature.
We created a Foreboding Forest, where the tree vines morphed, twisted and grew into DNA strands that whipped, lashed and attacked. Amber and the robot are the embodiment of Nurture fighting Nature (the Forest ) to control what Amber wishes desperately she can overcome.
