Mods used - PLEASE READ:

-AwesomeMod for slider multiplier, you'll need that if you want to edit the sim's features, and to remove the limit to the number of additional sliders you can have in game. If you don't want to install AwesomeMod, here you can get another hack to remove just the slider limit.
-Facial sliders by Ahmad. Just download 'em all :P
-UI Mod by Rez Delnava: you'll *NEED* this for the non-default skintone to show up. Otherwise, you're probably gonna get a scary boogeyman with no eyes, instead of Nikki Sixx.
EDIT: the UI mod is not updated for patch 1.17/Late Night, however you don't really need it anymore for the non-default skintone to show up: if you install non-default skintones, in fact, the game will still recognize them: read the note added by the MTS staff on the top of the UI Mod page to have more infos on how non-default skintones work in game
EDIT #2: added a version of the sim packaged with default skintone
