It looks like you got all of her most identifying features. The biggest issue I see is not with her hands (I like the center image the most though), but with her proportions. Look at how big her head is compared to her shoulder in yours, and then in the reference.
Here is her shoulder superimposed on her face:

See how her shoulder covers her head completely?
It's almost impossible to see, when you're working on it, how out of proportion things get. Proportions are also one of the hardest things to fix later on, so getting them right early will save you a lot of frustration.
Two tips to keep yourself on track:- Compare parts of the image that should be equal size to each other.
- Mirror your work occasionally (it's amazing what you'll see).
I see a lot more juicy details that you could fit into your portrait. I'm short on time, so I'll just post my edit for now. Mostly rough. I focused on trying to capture her attitude, and make sure everything was in proportion.
