hmmm...actually I think the "white detail" that makes it.
Creative use of lens flare creates a pretty interesting feel to it. I would play around with it some more (rather tweak it...) to see what would happen. Adjust the contrast and whatever. Also what hurts this shot a bit is a lack of sharpness. I think if the faces were rendered a little sharper it would help.
thanks Anthony I agree with your comments about shaper image would help I have played with contrast to bring out the lens fare but so far this is the best one I've come up with
