Thanks a lot for your comments!
Yes, the initial variant was an portrait of real girl in illustration style. But now I see two different ways of improvement of this picture realistic and stylized.
First I planned to make the basic light source on the right and to draw beams of volumetric light.
But now I see, that the variant which suggests Evicted in a combination with abient also is interesting. Before the beginning of this work I considered this variant of illumination in different photos (I made the photos of model with a candle also) and it has seemed to me too dark and red. A problem that it is difficult to draw a portrait of the real girl when the light source is located below. Because it imposes specific shadows on the face and it is difficult for making it looks like original.
I think, that wings it is magic object. It should not be adhered to priestess, because it not an ornament and not real wings. It only blessing of goddess Isidy caused by a flame. I shall try to make wings transparent for the better understanding.
Here is working process step by step: http://free-art.at.ua/publ/2-1-0-1

The best illustrations look believable, and need NO suspension of disbelief. THAT is what being a good artist is all about, and that is why critiques point out those visual discrepancies....

If you have to suspend your disbelief, then you are only admiring the pretty colors and shapes, you are not able to appreciate the artwork as anything more than just a picture...There IS a difference...

agree with a lot of what David says but most of it doesn't bother me and for me it doesn't distract or damage the image at all. i do like the style but i also agree that there is something about the wings that make them look too far set back behind the woman. and she is missing some sort of chest brace that would be attaching the wings to her.

but given the style and that I assume its not meant to be a realistic representation but rather an "illustration", i can suspend my disbelief about any of the inaccuracies there may be.

It's nice enough, I guess, but it really looks so overdone and unrealistic, that is too unbelievable to visually enjoy.

The lighting is inconsistent and over-exaggerated. It gives this piece too "plastic" a look, with no real consideration of how the light would reflect/refract from the different surfaces it is striking ~ Stone, fur, metal, skin, hair, pottery, fabric. They are all lit the same way...

Your other image also shows lighting problems. Effective lighting can cover a multitude of other visual sins, but bad lighting can detract from the most perfect of images...If you work on improving nothing else, I suggest you put some effort into more consistent lighting.

The wings look SO contrived and fake on her. They also look like they are behind the weird looking cat (that looks NOTHING like a cat, or a leopard, or a panther ~ it has a face like a cartoon or a "furry" anthro...). Since the "wings" are metal (they didn't have lightweight plastics back then), those suckers must weigh a TON...My only curiousity is how the heck they are mounted onto her back without pulling her shoulders down and WAAAY back...lol!

The flame looks totally fake, too, like some sort of glowing worms doing a dance on the dish, and the "smoke" appears to be more weird fire, making the eye wonder what it is looking at.

I don't know how many hairstyles you referenced, but those braided plaits were never a half-inch thick in size, even as wigs. She sure as hell doesn't have THAT much hair on her head...

It's nice, but just too overworked, with not enough "practical" thought given to what you are illustrating, with the result being that it just looks extremely unbelievable on any level, fantasy or reality.
