Zebra and foal drawing

Working on a new drawing of a zebra and foal,part of a group I encountered in Moremi game reserve in Botswana.
The animals were in the shade during the heat of the day and so the drawing depicts the animals mostly in shadow but with a few lovely highlights where the sun penetrated the tree cover.This is again quite a small scale image and because of this I opted not to stretch the paper beforehand in order to eliminate my usual preferred texture allowing me to use my clutch pencils for finer detail than I can usually achieve at this scale with wooden barrelled pencils.
