Bride on White Background

What do you think about this one? Good framing/composition? This was

a candid shot in between a more serious photo shoot...

too much blank space for me. she is beautiful, though

Pretty, but isn;t the background a touch gray? Maybe that's my monitor.

The background may seem a bit grey. It was natural light with no flash. On second thought, there may be a bit too much blank space, although I was trying to crop to keep the rule of thirds. Maybe cropping out the blank space on top would add.

I'd crop a bit away on the top, but that's all. The big white area on the bride's left is perfectly right for me. And of course I like her expression which is not always easy to achieve on a wedding day.
