A face a week (2)

I´m still working my way slowly, slowly, slowly, through the exercises in Carla Sonheim´s Drawing Lab book. I´m not quite managing a face a day, but am settling for a face a week now...

I´m also reading Misty Mawn´s Unfurling book, and am quite keen to try painting portraits at some point. But I´d like to practise drawing the faces a bit first. I´m not too sure how well I´ll go at adding colour.
Anyway, I drew this from a picture. I loved the girl´s huge expressive eyes, and slightly disbelieving look. I´m not sure whether I managed to capture that...
