Tanks are hard to draw - for me, anyway. My early years of doodling in school mostly consisted of animals, monsters, and videogame characters. Cars, motorcycles, guns, swords, and the like never really made their way to the page.
Chibi-tank is a bit of a compromise. It's got ears, choro-q-like proportions, and a cute bunny decal on the front. Vectors coming soon.
