The good things are that she's well placed in the frame, in focus, and pretty!
This particular framing is an idiom that's been used a lot. It's a common "environmental portrait" idiom. What you do, though, is place the subject in a relevant environment, so the background is also a composition, worth looking at, and (this is the important thing) connected with the subject. If she's a painter, put her in the studio. If she's a writer, put her where she writes. If she's a clerk at the grocery store, put her there!
Then put the background in focus as well.
The background here is soft, but not blurry enough to make us ignore it. The picture on the wall is crooked. And, there's no sense that the background is connected to the woman. Maybe she lived there? But that's just a guess.
