The Protagonist:
Referred to in the credits as "The Artist", she is a woman who has suffered at the hand of the law in horrific ways. Not so long ago, she was expected to give birth to a child. However, the government forced her to have an abortion and forcefully removed the child from her leading to a miscarriage.
Ever since that happened, she has laid low from the outside world due to the law against creativity. She has chosen to become an extremist of sorts and actively goes to an abandoned garage where she has set up her own secret art studio. It's here that she is working on her masterpiece; a painting of the fetus that could have been her living child.
To show the commitment she has to this work, she paints on a large sheet with her own blood; extracting more of it when she needs more to paint. This has resulted in her entire body being covered with scars, cuts and bruises as well as extreme blood loss. It's only a matter of time before these wounds take hold of her health.
For her costume design, we've decided to make her wear a tank top so that her arms are permanently exposed for her to extract blood. Upon arriving at the garage, she wears a blue shirt. This is because; in accordance with visual components theory, blue is the extraction of red; literally what she's doing with her own blood.
The Antagonist:
The three "police" represent the true antagonist in the film: the governing authority of the story's world. It's their job to hunt down and arrest anyone known to be breaking the law and creating illegally. At face, they seem to show no mercy beating their targets and hauling them away into prison. However, when they break in to find the work of the protagonist, we're reminded that they are still human as they express shock and almost fear; as if they begin to question if what they are doing is morally right.
