This series is going to be fun, I can tell. I'm flailing around madly trying to figure out how to make it do. ( 'How does make do?' is a common refrain at my house while dealing with electronics, photography, and elementary plumbing repairs.) But I'm pleased by my spasmotic twitching, because it means I'm learning. As I've mentioned before, rapid and not necessarily linear changes in style are a strong indicator of learning. (Check out the difference over a period of months between a webcomic like Questionable Content, where the artist has only been drawing these characters for a few years, and Girl Genius, where the artist has been well established for a long time.)
To bring this back to specifics: I really didn't do a good job on the areas of high contrast here. (Oops.) The fur is full of abrupt changes that aren't particularly well mapped to the topography of the surface they're supposed to be describing, and the gauntlets of the male look absolutely plastic. However, the skin shading and arm wraps on the female (the parts I did last) actually look pretty good.
From the Wowiki:
Centaurs are a half-humanoid, half- horse, war-like tribal race. They abound in central and southern Kalimdor, primarily in Desolace and the Barrens, where they engage in constant war against other centaur and Tauren tribes.
Each tribe of centaurs is lead by khan, who is generally a leader of above-average strength and intelligence. Some of the clans, if not all, practice cannibalism and will eat the flesh of other sapient races as well, such as the Tauren.
Centaurs follow a shamanistic faith, but their brand of shamanism is far different from the more gentle practices of the Horde. Curiously, most centaur shamans are female.
Filthy creatures, centaurs are always followed by swarms of flies, which are attracted by the centaur's repellent odor. Centaurs have no qualms about leaving piles of dung strewn about their encampments, and no concept of privacy.
