Zebra Foal drawing

Still working on the stripes on the neck of the zebra.The stripes have been layered with H,HB,B,2B and 3B in order to get the lovely deep black that i wanted.Because the animal is backlit the majority of it is in shadow and so even the white areas are being layered with H and HB even B in some areas with hair details added in with a 2B pencil.I am not going to put too much detail into the neck area as i want to acheive a photographic look to the piece by concentrating on the detail in the face and ears and also by trying to depict the bright white backlit hairs around the ears and face of the animal.
