This is a doodle of a wyvern made when I was 12. I was inspired to draw wyverns from seeing them in medieval manuscripts and thinking that they actually could exist, unlike the 6-limbed dragons. My wyverns have evolved to have dog-like heads, bird wings, and dinosaurian bodies. They spit poison instead of breathing fire (which some animals actually do). They are quick, maneuver well, and strike their prey in the face with their poison. Done in #2 pencil on cheap scrapbook paper.
