Not-quite-human, indeed. Wonderful job on the hair and skin texture. Delicious color scheme, though some greens mixed in with the hint of pink may have done a little more to deepen it.
I'm also having a tough time actually "seeing" gray when I look closely - if you did use neutral gray, I can't spot it. Superb job on that.
I must say that I like the sharp lines of the style used here. However, this exact thing makes the lips look slightly off. It may, however, be the large chin and indentation next to the mouth, so I'm unsure.
All in all, great style and interesting execution. Certainly unique, though I would have liked to have seen just a bit more - even a simple jewel or bauble in her hair.

There is a fair bit of turquoise mixed it, though it's fairly subtle. As for neutral gray, I didn't use any. It's all very light blues and pinks.
The lips are a tad off, yes, though I'll be damned if I know what it is. I did fix the chin a tad, however.
Was more of a personality thing to have her so naked, she's not the sort to wear jewels and such.
Thanks muchly for commenting.
