It took just over 3 hours to craft her. Specifically changed the skull, forehead, ears, eyebrows, eyes, nose, mouth and the entire jaw, literally every aspect was carefully tweaked using multiple faces, 2-3 at a time, for example 25/40/35, and that's after choosing 3 of the 10 heads for each category such as nose.
There's definitely room for improvement in the character creator but you can already achieve a great deal as it is. There is no way someone will randomly make a character that looks similar to mine.
(I made this character back when the creator released on PTU, and took a screenshot of every section (showing the faces and slider %) before I finalized it, so I could just go back and replicate it in 30 seconds, I suggest everyone do that.)
