You probably don't want to hear this... But I actually think it looked slightly better before. But what I feel is a problem in both pictures is that her nose is sort of "fleeting around" in her face. I think it's to do with a few different things. First off the construction isn't really there. It doesn't feel like the nose is following the perspective or the form of the rest of the face. Secondly that very sharp shadow around her nostril which quite unnaturally emphasizes the roundness of it, sort of makes it feel like that part of the nose is floating above the face.
It also seems like the upper part of her head is way too big. It wasn't really visible before when it was cropped out of the picture. Check the length from the eyes to the bottom of the chin with the length from the eyes and up. This should give you a rough idea of where the front edge of the top of the "head box" is.
It's still early (and perhaps a bad photo as well) but I'd like to see you push the values quite a bit more, especially around the face, to really make it pop.
