Have you been able to make an accurate simself?

My avatar is my simself, and I think she's extremely accurate - of how I looked 30-40 years ago. Why on earth would I want to make a simself of my old carcass now? :lol: But yeah, I got opinions of those who have known me for a really long time and they agree she's pretty spot on. I did use CC, though. It took me months to find the right moles. Her neck is too long, but that's the biggest thing "wrong". Is there a way to change neck length in S4? I couldn't find it if so.
