This piece definitely draws me in and just makes me stare at it for ages. All the different textures you have going on, in the mist and the hair and especially the prickly nest (?) in the tree, all of them just make my eyes giddy with delight. I love her face especially, so mysterious and beautiful and mask-like.
My only criticism is that a few of the details seem rushed to me. The mist creeping in on the edges feels a bit like you just used a stamp brush for it, and the lace under her skirt would have been an excellent place for some more eye-boggling detail and texture. Some more tones on the tree could have added a bit more depth, but that part is entirely up to your vision.
