Changed her facial structure, hair, and makeup. Also made a few other minor modifications here and there, including her voice. Oh, and one more thing: I changed her default outfit to "NONE" so she will appear naked if you have any nude body mods. The reason for doing this is so that she can wear anything that you give her. I guess this shouldn't be a problem as you are already just one of "those people" who downloads one of "those mods." Anyway, I hope it turns out all right!

To get the same result as in the screenshot, you must have these mods installed, although THEY ARE NOT NECESSARY IN ORDER TO GET THE MOD TO WORK:

I'm not really sure if this will work on other setups than my own as this is my first mod I ever uploaded, so give me feedback! Although, if there is a problem with it, I cannot guarantee that I can fix it since I my modding skills are so limited. Sorry!
