Check your histogram and you see that the assets are overexposed:

1) should be deep black

2) noise reduction destroyed details. In addition, the hair streaks are blown out by the overexposure.

I agree that the White Balance isn't quite right and the backgrounds overexposed a bit. 

Hi,

I would say overexposed, to few areas that are not blurred.

Hope that helps.

Overexposed. Greens are washed out and should be much darker. Bluish cast on the boars. Focusing issues possibly related to shallow depth of field.
