It's really pretty, I like the pastel theme to it. Your proportions are really accurate, and the position makes sense.
I love where the color in the hair changes from dark to light, it's smooth and you can see it clearly. It's a really lovely piece. The outfit is unique as well. The details all match and blend into each other really well without being the same as the rest of the outfit. I think you could make the nose more defined. (I know that's hard sometimes) Other than that, I think it looks wonderful! ^^ Keep up the good work!
