Doppelganger idea and make-up

As my film opening involves a doppelganger, I decided to take inspiration from Tomb Raider Underworld, as the main character, Lara Croft has a doppelganger that looks like her in the game.

One thing I noticed was that the doppelganger is far more pale, and her hair is red as well as her eyes being yellow.
I took the idea of the pale skin and dark area around the eyes and tried to recreate that on myself

In many films that have doppelgangers, they are shown to be stronger and faster compared to their real counterparts, as well as being evil. The slight difference in appearance is also very common, as doppelgangers are not exact duplicates of the original person, but very close copies, which is how they are often identified.
