i like the glow on the gal's face - however i find the angle does not benefit this pictures. I find that the guy's shoulder seems a bit too broad. I also found the four fingers a bit sengek.
Being a bit further away may have made it a much better shot... Like AZ said, the guy's shoulders look like they're dominating the center frame with one big white triangle. The girl's right-hand fingers seem to be growing out of his back.
Good work capturing the ring on her finger though. But if there were a stronger lightsource that caused a glint off the ring (maybe with a star-6 filter?) you'd have more attention on it.
