I am responsible for the drawn character design on the right and the 3D model.
The drawn concept on the right is by me.
I compiled the other references for different proportions, costume design, and hair design. She is a spy. Inspirations: Black Widow, Gogo Tomago, Sergeant Calhoun, Agent Hill, Yelena, and Mal.
