Pretty nice!
Really nice piece. Good soft shadows, and I love the classical, "Pisces" lips. It's a detail that really goes a long way. The way it's rendered reminds me of a classical style except with some more modern flair. The composition, the blue hair, and the eyes are certainly more modern ideas. I think all of it works, except the eyes. The extremely large, bright, and reflective eyes feel out of place. They look almost pasted on there like doll eyes. Although the shadow added under the eyes certainly help integrate them more into the face, but I think the idealized shine, size of the shine (Since the highlight is very intense) and size make them stick out. I notice that the irises are copied and pasted while everything has a much more natural, asymmetrical assemble to it. That could be another reason.
Overall though. this is some really fantastic work, and what I said above is really just nit-picking.
