daz 4.8 iray render usually use premade characters and or morphs to reshape features to create unique characters and sometimes a plugin called skinbuilder pro that allows you to create different skin colours, eyes, makeup, eyebrows and such with these can create unique looking characters just like in a lot of video games, this time around besides those I used a plugin called headshop used to be called faceshop in earlier versions, this allows you to import a face texture onto a character kind of a hit and miss though but if done right it is sort of like a latex mask on the cgi character model allowing you to have all kinds of expressions unlike if you just photoshopped/paintshopped someones head/face onto a photo. Anyway even though I didn't sculpt shape the head and her features right and she looks completely different here I used my sister in this one
