Wonderful hair. This shading is awesome! O_O
The skin shades are great too, but it looks like you forgot just one lighter shade on the skin (but perhaps it's only due to the bright highlight-line in the hair..?).
The style-mix of bold outlines and gentle shades is interesting. I don't know if I like it, though...
(Beautiful expression and great anatomy btw.)

I like the contrast between the bold outlines and gentle shades, also love the hair, looks so soft and washed with a very good shampoo :D. I agree with Kaminari, although I don't feel it needs heaps of (more) highlights on the body.
