The problem I have (written that too many times now) with this image is that although you have put admirable effort into the detail and texture of the drawing (especially the hair), the actual underlying basic line-art doesn't seem to quite sit right in my mind - for example, the jawline to me seems to be far too wide and really very masculine, and the eye sockets and recesses seem a little oddly shaped and it makes me feel sort of confused if I look for too long.
Maybe you're bang on the money and I just have some underlying issues with the facial anatomy of Asian people, but either way my opinion stems from my interpretation, and there it is.
