Greating. Depicted in the art creature still hasn't sustainable name. Definitely this creature is relative of centaur, but he (well, it's he) has wings. Inter alia reasonable creature is relative of Hallos'nai. Both have a devine origin, that brings they to the Elven race. For now I call him Alhataur (from Latin ala - wing, Sinai's (the fictional language) ha - horse and centaur. Later, when I with my friend contrive his name, I'll give it to you (and suitable art, certainly f-).
About locality, Alhataurs live (or lived?) in the territory of Emerald Forests (it's common name for several forests covering territory of Sinai's state - IyShar). The art shows alhataur on the cliff top. There are a lot of crags and mountains in the Emerald Forests.
About flaw. I didn't draw cloud in detail that its splendor not eclipsed the main figure f-).
Hope you love it †-)
