Well it's about time. I'm finally considering a new woodblock, a paleo-critter. This is the Przewalski's horse, or Takhi, the small Mongolian horse, the oldest horse in the world. Looks rather like something you might find painted on a cave wall.
This is one possible version, a kicking horse. Or it's mirror image:
I like the upright brush mane and the stripe down the back to the tail. Kinda like a zebra. Also short-legged with a large head.
