I actually entered this knowing it was a 'bad' image, I was curious what it would score and so many of my 'good' images score so low that it was just a personal 'test' . There is actually no lens flare in this image, but I do agree that it is blown out, the expresssion is 'blah' and just overall a poor quality shot.Thanks 4 the comments.
There's a lot to like about this shot. The backlighting is nice, especially on her eyelashes, and her expression is good. The trouble with backlighting, though, is that it's hard to control. Her forehead and the top of her chin are both a bit blown out, and it looks like lens flare has taken over most of her face. Sometimes that stuff can be fixed during post processing, but the most effective thing is to shoot when the sun is less intense, or shoot from a slightly different angle, to try to control things better.
