This is my latest 'Guardian', Cerbera, Hell Guardian. Originally a quick sketch in my sketchbook on the way home from London. I scanned and reworked in photoshop.

He has neon, electrical wings, rather than the skull, his skull has powered down, only reacting to it's 'prey'. this is his natural habitat, hell. when on the earths surface, the guardians lurk high up, watching over the dangerous, industrial areas, thriving on the furnace like air and poisonous atmosphere.
