This was the Tarkatan face with no hiding teeth.
Mileena with Kitana comparison
Early version, I was trying to design a mouth that looked normal, but fragmented into separate pieces. I referenced snake skulls for it.
This was the hybrid cross of snake skull and human skull that seemed like a logical function to Mileena.
I didn't get to do the sculpt for the game character, but I did pitch ideas for what her face could look like.
