Wedding shoot

Generally speaking, most people will react more favourably to a picture that has more space in front of a side facing person. As your subject is looking out of the frame, so to speak, cropping behind her would probably lift the whole picture.
That cropping would also eliminate the dark vertical lines behind her.
I would suggest you may wish to move this to the critique gallery, if you wish for some constructive comments.

Great shot that will be infinitely better by cropping.
I'm surpised she isn't pitch black with that backlighting. Nice job
