Botswana Buffalo drawing

This drawing in progress of a pair of old boy buffalo's chewing the cud is based on an encounter with a resting group of buffalo in chobe,Botswana.During the hottest part of the day they would lie down under the shade of trees and chew the cud until it cooled down enough for them to resume feeding into the evening.this is a small drawing in comparison to those ive produced of late at only 9" x 15" and another days work should see it completed.i love buffalo as a subject as they've got so much character and with those magnificent horns lots of textures to portray as well,perfect for graphite.i think,along with elephants, they will feature prominently in my works this year based on my trip to Botswana in September of last year.
