My opinion
Too much black.
Her hair blends into it.
She is very small in the frame in several, yet the rest that fills the frame isn't very interesting.
If you want more/better feedback...try to show only one or two images at once. Or at least add numbers to them.
Overall, I think these have too much contrast. The blacks are too dark (or at least there is too much black in the images) and the whites are blown out.
Also, she looks sort of miserable. What that intentional?
