This painting is quite impressive, though it suffers to deliver a complete astonishing effect. There are good parts, and not so good ones. The black feather wings for example are quite nicely done and organized. The designs on the head are also impressive and somewhat amazingly original.
The background fails to deliver its part, I disliked the choice of a white background, a different color would have made it look more appealing and striking. Of course, Technically, you are very good, but the implementation and use of your good technical ability is the issue, you need more practice on some aspects.
Her anatomy is kind of misdone, and again I stress how important it is to pick a good background.
