It's great!
I enjoy seeing peoples' arts & you could add a little bit of shadowing..because the other half of her looks a bit unfinished and some of the features seem a bit masculine..i want to say it's the jaw..but i know her jaw is a bit mannish..but it could be the eyebrows..maybe add a bit more detail into her hair & i think it could look better.
can't wait to see more of your work~ :D
