Sadly, not. I usually only draw realistic animals, and neopets have little to no anatomy; it's all much too stylized. But neopets that can be drawn similar to real life animals, such as lupes being wolves, kougras being tigers, or lutaris being otters, shouldn't be a problem.
If you threw a chia at me, however, or a kacheek, I wouldn't exactly know how to study its "anatomy" and then apply it to my own style.
