I decided to try creating a celebrity sim, and chose Dana Scully (Gillian Anderson) from The X-Files as my first victim. She got one of those stupid Exchange poses, but I've uploaded her so many times already that I just can't be bothered to try and change it again.
Here she is:

She's also portrayed in my signature, that's unfortunately the only ingame picture I have of her right now.
Here's a picture for reference:

Feel free to download and comment, I don't mind critisism either. :-)
