Not bad at all

I like the detail as well as the shading, very realistic portrait. My main issue is I'm not entirely sure what kind of expression this is and not sure what the feeling is, but regardless, it is still a very nice painting. She actually reminds me a lot of my wife, Chie; you claim this to be a self portrait, do you mind me asking if you are of Asian/Oriental descent? Chie is Japanese, so that is why I may see similarities. The right eye does seem a little disproportionate as well, but really only under harsh scrutiny.
