I decided to make EDI look more human and less robot-like. I've given her hair, ears, eyelashes. I took Ashley's original hair and took it to a barber, then made that EDI's hair. Changed the material settings on her scalp so it isn't shiny. Her "skin" remains shiny as part of keeping her synthetic looking, just more human at the same time.
Update and improvement to the original mod. EDI's skin is no longer shiny/glossy, her teeth are white, tongue red, her hair is brown. Her mouth animation is improved as is texture blending between face and scalp.
