This is intensely beautiful and purposefully rendered. A great number of light sources are considered, bounced, and scattered with a unifying intent toward composition. The work leads the eye around effortlessly, and is perhaps your best yet.
The only problem I can see has to do with proportion. Please see the following paint-over: [link]
Ignore the legs and line of weight as I only used them to check other things. The important metric here is in red. As her right arm is seen in nearly perfect profile, there should be no foreshortening of her humerus. You may not have been going for that anyway, but the end result is a tiny arm with an extended forearm.
I copied and rotated the right arm metrics (red) over to the left arm metrics (black) to illustrate this. You can clearly see the differences in length for both. Anatomically, her left arm is the correct one. The elbow usually sits at the base of the rib cage when at rest (the blue arc). I again copied the right humerus and swung it down (orange arc) to show you that indeed the arm is about two real-world inches too short.
And it's a shame, really. You've spent so much time masterfully rendering this and taken it to a finish before it was ready. It's like when you see a beautiful actress on a magazine cover; struck by her beauty for sure, but the moment you notice the photoshop artist removed one of her legs it's the only thing you can see.
This is SO weird. I swear I saw her last night in my dream--and the thing is, I've only seen your painting today. Just now. When I looked up "Faerie." That was exactly how she looked! Her hair, her clothes, the colors.... Weird.
