For ArtOrders HP Lovecraft contest due today. It's a Shantak.
"They were not any birds or bats known elsewhere on earth or in dreamland, for they were larger than elephants and had heads like a horse's. Carter knew that they must be the shantak-birds of ill rumour, and wondered no more what evil guardians and nameless sentinels made men avoid the boreal rock desert." —H. P. Lovecraft, The Dream-Quest of Unknown Kadath
It's a great idea to have the rear legs to bear the wings, instead of the front ones like birds, it adds a sense of strangeness to the creature which works perfectly well
that is deffenetly an interesting design. It's very impressive how you managed to come up with such an idea with just so little information from the book!
