Realistic graphite portrait of girl

"No one can lie, no one can hide anything, when he looks directly into someone's eyes." ~ Paulo Coelho

I found this portrait interesting and fun to draw The details, especially the hair, were difficult and took a lot of time. I finished this portrait over a period of two weeks on a Bristol board (30cmx42cm), I used a 0.5mm mechanical pencil and 4h, hb, 2b, 4b graphite pencils. I also used an electric eraser and putty rubber for the highlights.
