Wow, I love the way you drew her face! If I may be honest, I like it more than your usual style. The face looks a lot more refined and detailed, but also more mature. You've really given her 'character'. I personally think the face is one of the most important parts of a character. I don't know if you intend to go for this sort of style more in the future, but I do encourage you to keep experimenting. ^^
I also love her outfit. It's feminine without revealing too much. You can still see curves.
