Nice render, I like the image in itself. But I’m not sure the likeness is there, at least compared to the fotos (which may not be representative).
Nose should be longer, for example, forehead straighter, and some overall proportional relations are a little off, so that she doesn’t really look like herself (again, judging by the fotos).
Likeness is super hard, if you want to improve that skill, I recommend not starting with polished pieces, but rather doing many 1-2h sketches of different people.
Once good at that, you can take it a lot further with your great rendering skills!
