Man, my juices got going, which was cool, because I've gotta get into Monster Mode here shortly for some articles for TAG.
This is a quick sketch of a dragon inspired by a pic from a regular Facebook posting from the Zoo. Monitours are so cool. The blue one was the coolest. This is just a baby :P Still has its egg horn and everything. Judging from the bone, probably about 3 1/2' long.
