I've moved this thread into AD, since it's not a class question.
I can help you do anything you like with the background. You just tell me what you want.
You wouldn't have posted if you didn't already know I was right.
Sharpening exaggerates and enhances detail that is already there. It can't magically create detail that doesn't exist. Her lashes don't exist in this photo.

The next time you have a photo which you think would benefit from premature cropping, post it for me and we'll discuss why you're wrong.
