I added some g.blur (sorry i forgot the actual name).

Which one is much better from the two that I just edited. I know the crop isn't very good but I wasn't actually the one who took the image.

There is still some blue hue in their hair, clever saturation masking should do the trick.

Nice composition. I am curious as to why you want the blur.
