This is the kind of stuff I've been drawing my whole life. Whenever I'm doodling, or I just want to have some fun, I draw critters like these. Usually each creature starts with some random shapes. Then I flesh them out and add details like hair, scales and clothes. I think I may try to color this one, and maybe next time I do a group like this, I'll do a step-by-step tutorial, so you can see my process.
