Creatures at the moment, the have more various designs. Your humans, kind of end up looking alike. I'm missing something. The do look more dynamic every time, but you really should do more of it. It may be a good idea to do a comic page because you get characters to interact and talk to each other. Its far more different than just a pose with design. Also a short story tells a lot more about your characters. If you want I can help you with it. I want to make my story boarding better.
I like both, but I lean towards your creatures, as I guess I'm more interested in the subject than regular folks. Your ability to blend realistic animal parts with fantasy is excellent and you often make them in pretty colors which I appreciate
