Regalia...

"Regale" in italian means "Royal". This girl in this outfit really seems to be royal. If not a Queen someone in the royal court. The detailed outfit, his order and simmetric impression is wonderful. the curves and spikes in the details give the impression of a contained "chaos" (You said the outfit was possessed, right? I think you made it clear!)
But the real great thing of this picture is the expression of the girl, she watches you right in your eyes and you (or, at least, me xD) feel an anguish sensation, you feel like you're watching someone with an inner suffering, asking for help, not with the despair done by something ferocious, but by something which gives a relentless slow pain... If I have to imagine what she would be saying it would be "Help me... please I need it..."
In my humble opinion, I think you did a great work =)

Detail is key...
