Any help appreciated.
The overall colour balance is blue because your subjects are in open shade (under a blue sky) but your camera is set to give a sunlight/flash colour balance. I can't see any trace of your flash fill which would normally have overpowered the natural light with flash-coloured light. (Look at the eyes - no trace of a reflection of the flash unit).

The genarally soft look could be flare. You're shooting into the sun - you might have had the sun shining onto the lens surface, which you didn't see because you were zoomed out to tele.
