Alright, that's my first kind_of_a_mod, so hopefully I didn't mess up anything.
The mod was created with Face Ripper.

Installation:
Simple. Manually or with NNM.

The look was inspired by this art, but I couldn't quite reproduce it, so it became something different.

Among my mods I use:
Young Male Face Texture
Lots More Male Hairstyles and Lots More Facial Hair, but this mod only uses original hair and beard, so I guess these mods are not required.

Fixed his mouth a little. Looks better in static, looks better in animations.
The original version still arguably looks better than v2 if face-ripped to Sole Survivor (or other npc probably).
It was originally created on SS's face and then faceripped to Maccready, and for some reason it looks different on him. Weird...
