You do have some great sharpness and detail in this drawing, but there are a few flaws I'd like to point out:
1. Her right eye looks about half the size of her left one.
2. The second line by her nose is unneeded. That's probably something you just forgot to erase.
3. The rosy cheek effect you tried to do is just atrocious. It looks like she has a huge pimple on each cheek.
Like I said, you did a great job with detailing and sharpness. Personally, the thing I like best here is the sheen of her hair. Not a bad drawing whatsoever, but those flaws I found really hurt your artwork. Especially trying to give her rosy cheeks, which turned out terrible.
