Original mod has nice textures (Well, kind of, I still prefer Super Mutant HD - 4K ReTextures, this is just to spice nightkin up from time to time), but the glowing eyes are just too cartoony. I gave a quick edit to their nightkin skin with some proper eyes. You can use it either by installing it over the original mod, or as a standalone nightkin textures replacer, like I did. All credits go to the OG author, CaBaL120, this is the super simple texture edit.
