Nice! I love the colors here, and the use of sharp detail on things like her face, vs. the front foliage and the background mountains.
One suggestion--delete unread if you don't want 'em:
The cloak chain/necklace looks like it's supposed to be centered on her chest, but it's noticeably off-center in our direction. A lot of artists have problems with centering; the trick is to map it onto the body rather than judge it by eye.
If it were centered, the point of the V would rest in the valley between her breasts, rather than halfway up the nearer breast. (It's amazing how many people draw superheroines with skin-tight v-necks that, for some reason, cover most of one breast but barely clear the nipple on the other side when we see them in 3/4 view. Our eyes fool us....)
I like how ancient she looks, and that she doesn't exactly conform to the contemporary standards of beauty (by which I'm not saying she's not pretty, if you see my point). Was this perchance inspired by Alan Lee's rendering? It reminds me of it. ^ ^
