What is it with you and breasts? It's saddening.
Also, I agree with Cerro, the left side of her lip (it's on the right in our view) could use some work.
Well as I said before she's beautiful, but what she's missing is color, true color. All this has is a pretty face and hair. I know you want to base it off of a person in real life, but I recommend adding a few bright colors (maybe a hairpin or a little colorful accessory on the glasses).
