Crop is too tight at the bottom, as Alpha says. Exposure and focus look fine. Is that you in the reflection in her eye?
I agree that the crop is a bit too close at the bottom, but the exposure is perfect. While some might consider the depth of field a bit too shallow (a lot of her face is not in focus) I think it really softens her face - she's beautiful by the way. I love the strands of hair falling in different diagonals.
its cut off because this was just a snap shot of a friend while i was doing a different shoot lol. I saw it and liked it so i posted it
