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 skin and scalp so they are no longer shiny.
For those with the Collector's Edition, my mods will sometimes fail to apply to your DLC (because I don't have Collector's Edition). This mod provides the instructions, meshes, and textures necessary to get the mod into the Collector's Edition manually.
