The background would be mostly ok if there were no girl in the photo, but shadows seem to have been crushed. One issue is that she is wearing a black dress. If she were wearing yellow or white, she would stand out much better, although her face is a bit dark. The biggest issue is that blacks are crushed, so all detail in her dress is lost.
In a few seconds, I made this:
Attachment 257758
I applied a local adjustment brush to Julie of +0.29 Exposure. I applied the following global settings in Lightroom:
Exposure +0.24
Shadows +14
Whites +36
Blacks +71
Clarity +2
As I said, the blacks had been crushed, so the biggest bump is in the black level. The whites were pretty low, so a bump in them brightens the muddled parts of the image.
