Yeah, usually I like your BG as it's typically subtle. But this time, it's really bulging out with the lighting, and the lighting and texture is pulling the attention away from your subject. Since she's not looking at us, and is looking away in the direction of the lit area of the bulging BG, that helps take attention away from her.
Do me a favor. Re-post this shot with just a normal gray background. My money says this shot of her just pops when you do that.
