Artist James Doyle has the perfect name for his flightless griffin creature: Old Chicken Wings.
Doyle is a sculptor and digital artist who has more glorious creatures up at his Facebook page. You can also see some progress shots for Old Chicken Wings up at his blog. He physically sculpted the figure in Chavant and then painted it digitally in Photoshop, a combination which makes this griffin look like it might spring to life.
