That Jyn Erso is a possibly a droid. The side of her face blending into the face of the Death Star. A droid created by her father as a counterpoint to the Death Star. He knew he would be forced to build a Manhattan Project like monstrosity for the Empire, so he in secret created a weapon to fight it. A droid that would bring hope and help to destroy his dark creation.
Either that or it's just the thematic beat that his natural creation in a daughter helps to destroy his evil technological creation. Furthering the ongoing theme throughout the Star Wars trilogy that nature and the force are far more powerful than technology.
