There are so many different levels of beauty here that it still surprises me. You've captured a perfectly mythical feel for this character and I congratulate you on giving a bat a different personality other than a gothic or dark one. I have to say, when I first saw this design I didn't realize that she was a bat until the wings and ears gave it away. Her eyes and face actually remind me of a desert cat species. Don't worry. It complements her absolutely.
This is beautifully done. Over all the bat priestess looks beautiful and I like the angle of the picture. How you get a view of looking down at her. And her eyes are really pretty. The armor and clothing not only have a nice design and shine to it, but also helps bring that out on her face.
The colors are just as amazing. I really love the shading and lighting. And wonderful textures! especialy in the wings and her fur.
I also like the expression. I wonder what she was up too or what she was doing.
