Well, I think the head is still way too big. Also the relative scale of the body parts is off, as well as the placement of the features. On the bright side, I think your handling of the paint is very nice.
To put a fine point on it, there is absolutely nothing that can save a painting that has a flawed drawing. You've made some changes, I can see that, but I think you're going to have to hike up your socks and make more drastic adjustments.
I empathize with the situation - it's hard to make sweeping adjustments when you don't want to lose what has already gone right in a painting. I think her pose is very sweet and communicative, but it is lost in a tight composition. You may want to consider calling this a study, and moving on to a larger canvas, where you can spend as much time as you want getting the drawing precisely right.
I'm not trying to discourage you, by the way. Just the opposite!
