El Cuervo - character design

Hello everyone! A little while back I sketched this little character and after the positive reception he got I decided to go more in depth.

"Amongst the rocky cliffs and small dry bushes, a mysterious figure lives on the outskirts of the desert. Nobody really knows his backstory, purpose or has seen his face for that matter... What people do know about him they discuss in hushed tones... Swift, agile and cunning, he seems to elude the local authorities like a seasoned desert snake. Is he good? Evil? Who knows... He is simply known as El Cuervo... The Raven."
