So the first thing I think the colors together beautifully. What bothers me personally something, is that her face is too much in the shadows. It'd better come into play when (paint) them there would be something more to spotlight.
It would also look better if the lady in the picture would be slightly higher overall. For my part I think the top of her head wasted space to the brim.
Otherwise, I like her hair, hair ornaments and dress very well. The delicacy of the Lady speaks especially to me.
All in all, it has become quite beautiful. I hope I was not too hard - I'm trying to be objective but and it's just my own humble opinion.
Way to go, I'm looking even more beautiful pictures of you to see.
