It really depends on what your concept is for the photo. What did you want to communicate with it?
Virtual, I agree with Ms. P. The warm tones that you have presently give the picture (at least in my mind) a very warm feeling, maybe even intimate. If you adjust the white balance, obviously, the whites come out and give the picture a whole different feel and I think the centerpiece would stand out and "pop" more. I am not sure what the change in WB would have with the background. maybe play with it and post both side by side?? Was the camera set on AWB??
