Korax the second Serpent Rider from Hexen, an old game but one of my favourites. Powerfull demon, is the second in command of three brothers, the oldest and more powerfull is Eidolon, then comes Korax and the yougest and more weak is D'sparil.
Well this is my version of Korax... in the game you cannot see him very well so... I believe that he is something like that. Made with pencils 4B and 6B... 6B mostly.
