Your colors, composition and anatomy are too gorgeous for this world, but if I may offer a small critique; there doesn't seem to be quite enough definition between "objects" and it makes it a little difficult to really see the details of the body without looking closer. I realize it is a tough color scheme to work with (monochrome can be a bitch), and it was more on the experimental side compared to your usual art, but if there was perhaps a little more highlight work and color from her wings on her body, then it might help her stand out a little more. At the moment, all of the focus is on the wings and hair (especially the brightest part of her mane in the middle), and everything else becomes a little jumbled in the colors. Overall it just seems to lack an interaction between parts and appears more like a flat color piece. I still think it's a gorgeous piece, but if you would like to do more of these in the future, my only suggestion would be to define them just a little more, and to shift the focus more on her face.
