flower blown, eyes too blue though I think you are right keeping them in colour is a good thing. Execution wise thats my opinion but that is matter of taste rather than pure technical judgement.
Everything else I think is good, its good composition and the emotion is haunting.
You probably scored lower in this because of the selective desaturation I'm guessing folks who like the image composition and would have scored it 6 or 7 dropped a mark.
If I had voted (and I don't in challenged I've entered) I would have given it 7 then maybe bumped it to 8 if I wanted it to win.
I thought this was adorable and gave you a 7. I didn't really like the partial desat though so you would have gotten a higher score from me without it.
In my opinion, based on my preferences, this would be a much stronger shot without the blue but that's because I'm not a big fan of the partial desat thing. I love the odd angle and the flowers above her head to echo the one in her hair. She has a great expression. Minor nit - clone the white petal on the lower left on the ground and MAYBE give it just a bit more contrast, but not too much. I quite like the shot - quirky and fun!
