I just changed how Ria looks a little bit. Basically I removed the dirt from her face and made her look a bit younger. I also set her weight to the minimum. I tried to make her look more "cute", but I didn't really succeed as much as I wanted to. It's still better than vanilla in my opinion though.
I also gave her bracers to go with the rest of her armour.

No mods are required to run this.
Of course any mods that somehow change how Ria looks are incompatible.
If you want a different mod that changes how Ria looks (in addition to other things) and this mod, you could try putting this mod below the other mod in your load order. I can't guarantee it works though.

If you want her to be essential, I advise you download and install Extensible Follower Framework: http://www.nexusmods.com/skyrim/mods/12933/?



If someone wants to add this to their own mod, feel free to do so. Just credit me and send me a link to your mod.
Unless it is a paid mod, then I would first like a discription of the mod you're making before I decide if I agree with you using this.
I do not condone uploading this somewhere else and asking money for it. This is a free mod.
