Landon Meier is a mask maker also known as "Hyperflesh." He creates hyper-realistic silicon masks, and this adult-sized "little girl" mask is a perfect example of his work... gone completely horrifying.
There's something just supremely uncanny about the face of a little girl the size of a grown man's head, on top of an adult body. It probably also doesn't help that "she" has a motionless face and dark, dead little eyes.
Hyperflesh has also created masks for public figures like Donald Trump, Vladimir Putin, Kim Jong-un, Mike Tyson, and Bryan Cranston.
