Too busy and it's too light in the wrong areas so the attention gets drawn to the background instead of the subject. Unfortunatley not fixable so bin it and move on IMO
Yeah, the scenario of the shot was working against you. It was a great real life moment that just didn't quite translate in the image. Keep your eyes peeled for the next one and hope your subject is more cooperative in finding the lighting.
What you see and what comes across in a photo aren't always the same. Sometimes it works better, sometimes not. I agree with both responses above. That is why I try to snap as many of the same scene as possible. I know moving subjects prevent an identical set, but sometimes you just have to take what you get.
