Howdy great peeps,

I present to you Vanessa, a very pretty girl.
This save is after leaving the vault.

If you only want the face I suggest to use this tool to transfer it to your save:
http://www.nexusmods.com/fallout4/mods/3878/? - One of the best tools there is!

Update 1.2:
I added an alternative version (see images), that has a slightly thinner face, 
different hair & basically all categories slightly edited (I also added 3 hair color choices).

To edit her anywhere:
Open up the console (whilst in 3rd person view),
then type 'showlooksmenu player 1' (remove the ' ' from the sentence) & press enter.
(If the camera doesn't set it self - simply go to the body section & back,
after you leave the creator & the camera doesn't revert - draw/holster a weapon)

If you have a big Pip-Boy inventory screen, do this:
Open up the console (whilst in 1st person view), ~, then type,
'fov 92', then press Enter - then type 'refreshini' & then press Enter again,
then you can close the console (remove the ' ' from the words above).

Enjoy.

Kind regards,
Mike
