That's really nice-- I like the lighting and the expression on her face... Constructive: Very nice set of the face, but I think we're missing the shadows for the eyelashes. In such a heavily shadowed image, it does stand out. I think you could do with a bit more detail in the texture map. Bring out her eyebrows (I don' t see any!), her lips, and a bit of colour on the cheeks and forehead couldn't go astray. The texture map is half the character, as far as I can tell. I do love the expression-- I can see a lot of careful work went into that!
