Brought into Lightroom... corrected white balance, clarity to 45, vibrance +1, modified curves in both shadow and blown highlights to bring back in range. Also added a small vignette to edges to highlight your daughter.

To avoid in future, you'll need to better control white balance.. here, the auto white balance overcompensated for the severe back light and dulled the image to avoid total blowout of highlights.. shooting RAW would have been easy to correct - I did ok with the jpg but of course the image resolution suffered a bit.
