Vigilant 20 x 25 inches on Stonehenge with Faber-Castell Polychromos pencils.
My friend Terry, went to Kenya and shot a beautiful photograph of this cheetah family. He gave me permission to use it as a reference. The sky and plains in the background were not in the reference and were added in such a way to elevate the cheetah family higher than they were in the original image. The entire progress in the drawing can be found on WetCanvas in this thread
