I always love drawing skeletons and zombified animals. Here are a few I drew in my spare time
They are drawn with regular pencil and some colored with colored pencil.
Zombie cat (sorry for bad quality, to big to scan so had to use camera) I'm hoping to some day redraw this digitally or have it redrawn and made into a car graphic.
Zombie cat sleeping
Zombie Doberman (inspired by Resident Evil, not colored)
Zombie Pitbull (drawn for my little cousin)
Zombie Pegasus (winged horse)
Demon Winged Horse Creature (not colored)
Horse skeleton (not scientifically correct)
