If you are not a Skyfem user, the regular NAO is here!

Skyfem is a great patch mod for those who want to play in a Skyrim with only women (or with Women and "Futanari").  But it does have one key downside:  it just copies "female" heads to give to the "male" NPCs resulting in duplicate and triplicate heads walking around (many more "male" NPCs in the game than "female").  and the skyfem script doesn't know how to avoid putting heads on NPCs that don't make sense (like a charred face on a nobleman, or foresworn face paint on a city slicker.  

This edition of NAO changes that.  Every NPC has been individually adjusted to have a unique look and this was done one by one in CK not via a script.  
- Exceptions:  if you have NPCs in your Skyrim from mods not covered here, then those NPCs would have faces copied by skyfem.  I cover over 2800 NPCs here though, so surely a vast majority.  

The aim here was for beauty and variety.  To improve beauty and variety I went beyond vanilla assets to include:

- high poly head (all playable-race female NPCs get this)
- high poly versions of: vanilla eyebrows + Koralina's eyebrows + SG eyebrows
- eye textures from: vanilla + Kala's + my own custom ones (including some larger iris')
- KS hair
- makeup masks from: vanilla + Koralina's makeup tweaks
* with all the above assets I was able to create way more permutations of facial variety *

Installation:
install Skyfem as usual - so after you have all your other mods (except this one) ready to go then run the skyfem script.  
still install the contents of "dummy file" created by skyfem as you usually would in case you have any NPCs not covered by this mod
good idea to play-test at this point to make sure your Skyfem install was good
then install this mod.  IPORTANT: overwrite skyfem created facegen files with the ones in this mod

manual installation is not recommended for mods with hundreds or thousands of facegen meshes or you'll have trouble knowing which to remove, what has overwritten what with multiple replacers etc.  

Also Important:  since this needs to load after skyfem it's gonna be really late in the order and will overwrite just about any mod you got... so if you have a mod that adjusts an NPC file of a vanilla or DLC character a patch will be required to forward the changes that mod made (or just forward the change to this mod's esp in xedit). 

you can just use this as a better base than vanilla to add your favorite NPC replacers, just ensure that both the esps (if any) and meshes of the replacers overwrite this mod
