I've had this Rat Fink-inspired pumpkin biker on my mind since last Halloween when I did the character portrait. I love those old wonky cartoons you'd find in car magazines, peeling out in some Looney Tunes looking vehicle with their eyes bugging out.
The character is my own (but obviously inspired by Ghost Rider and a bit of Sleepy Hollow), tentatively named Jacko, formerly Jack O'Briar, a biker left dead in a pumpkin patch, resurrected for vengeance after lightning struck a pumpkin. The vines and roots interwove with his bones to actuate his skeleton around. The light in his head isn't a candle- it's the burning of his very soul. I have a comic in mind for it all but no time to do it just yet.
His bike is 'Ursula', no real reason other than that came to mind.
