How to getskin tones right???

[Leedoc]

Hi, Im new here and I just getting back into photography after a few years off, so would love any help you can give me.
Im having trouble getting skin tones right on my shots. Im not sure where I am going wrong, is it in camera, am I not getting my exposure and white balance right ( I dont use a grey card..maybe I need to get one). Or am I losing it in pp??? Ahhh I just dont know and it is driving me mad. Any help would be great.

Here is my SOOC and my attempt with pp. Her skin is very grey/pink in the SOOC and grey/yellow in the edited.

Thanks Lee
