I disagree in that as well. If you were to show that to a client they would make you do more. I'm not dissing your work, you nailed the skin tones.
However you simply CANNOT have hair frizzed about like that.
I don't know what experience you have in retouching, as this being off of a tutorial; However I do not appreciate being told i have no clue on it.
That said, next time if you don't want actual CnC don't ask for it.
