This kind of shot is tricky...it's very much about gesture and body positioning. I think cropping off the two lights at the top and the back of the guy on the left helps...but this shot is really not great source material even for a heavy crop. Does this seem any better? The problem is the exact timing and body placement of the actors...not everything was optimal when the shutter captured the scene.
Here's the crop. The two boys in white shirts are the most annoying out of place details...
I wouldn't mind not seeing the faces if there was dramatic and expressive body language. In order to capture the emotion of a moment, you need to capture the most intense millisecond. For instance, if you were photographing a yawn, you need to capture it at the height of the yawn, not when the mouth is halfway open or halfway closed.
In this photo, you attempted that by capturing a dramatic moment of the dress. But we want to see it in the people. Everyone is sort of halfway in between moments. There isn't any expression in their bodies. It's just a matter of being patient and recognizing that perfect climax of movement.
