While cleaning out the backup folder I still had of my previous Skyrim installation, I found the presets of some of the characters that I no longer play. Over the years, some of those presets were requested by several members of the community so I thought I'd finally share them. 

Below, you can find portraits of each of the characters as well as a list of all the mods required to replicate their appearance. 

[1. Katexiora]

*Alternative Look:

Required Mods: {Race: Ningheim}
(1) The Ningheim Race by Seren4XX
(2) SRG Textures by Seren4XX (Off-Nexus). Replace the default Ningheim textures with those.
*For the alternative look, download the Abyssal Dremora Race (Off-Nexus) and replace both the skin textures (only diffuse, not normals) and the used eye texture with the ones you see in the screenshot.
(3) XCE Scars by Xenius (I recommend taking out only the scars)
