I'll see if I can list 'em, hold on...

:: Slim version of the CBBE body. I think there was an option in there that replaced the original faces of female characters, that's why she looks better than default models. xD
:: 'More hair colours', ...at least I think that's what it's called O_o It just gives you a wider variety. I only got it because it has a nice red colour.
:: Coolsims hair pack... I'm not sure if it's on Nexus anymore though. You'd have to do some searching. I only got it because of that one hairstyle I use for Aria, really.
:: The armor is called the 'Hedge Mage', kinda gives off a mercenary-mage feeling. x3
:: Higher Res textures DLCs (free) from Steam, and every graphic option on ultra. It's still not super-detailed though when you do that unfortunately. Makes the environment look -awesome- though!
