Ninja Turtles Sketches I drew these in my sketchbook, with different colored ballpoint pens. My intention was to sketch different versions of the Ninja Turtles. The dark blue one is from the newest TMNT movies. The purple one is based on the late '80s cartoon show. The green one is first comic book appearance ninja turtles. The light blue is from an animated show, I think in the 2000s. The red one was how I might draw a ninja turtle in comic book style. The black one was how I would draw a ninja turtle in my cartoon style.
