This is a very nice use of shallow depth of field to show off the sharp flowers against an out of focus background. The background would be very distracting otherwise. I am not sure what focal length or f-stop you are using, but don't be afraid of using your widest f-stop (such as f/4 or f/5.6 on many telephoto zooms, and consider using zoom at its highest telephoto setting and backing up to get the shot. Both of those things will make the background even softer and more attractive.
