Hey there,
thanks for looking and commenting on my doodle of Amy... I did indeed use a pen and also a brush (to fill in the larger areas with ink)
As for getting proportions sketch in pencil and keep rubbing out the rubbish bits until her face looked about right Grins
I did a series of "In progress" scans of this showing what it looked like in pencil with all the guide lines in... if you'd like to see them I can E-Mail them too you and then you can have a look and see how it was built up.

That is an awesome piece of work. Did you use a pen to finish it? What techniques do you use for face proportions?
