In greek mithology, a sphinx is a powerful being with the head of a woman and the body of a lion. I made this creature with the head of a pony (obvious) and the body of a lion (based on Gilda's body design).
Sorry you, but this and practically 90% of my art disappeared when I had to reset my computer during the summer. It was a big loss. But if you want to draw your own sphynx, it would be great to see it when you're done. Also, do you have a link to Equestria-Prevails' one?
