hhhmm, where to start [img]/images/graemlins/smile.gif[/img] Ok, well, its a decent start, but I wouldnt call it done if I were you, even if youre not worried about it looking like Cuthbert. She aint too hot at the mo to be honest.
toplogy looks very sound, general face shape good, if a tiny bit square jawed for female.
Eye shape. Take another look at a front ortho of a female eye. This shape looks a little strange and theyre slanting down too. Theyre also too possibly too far apart. Theyre too high on the face.
The way too hard line where the plane of the side of the nose intersects the plane of the cheeks.
Ears could use detail and and ref.
Lips. something odd going on there. Looks like she has a huge lower lip perhaps.
Ears are too high.
Did a quick paintover. Hope this helps to see the quirky stuff:
