The bald white sky takes much away when showing the sun drenched foreground. Filling in the sky area with a very pale blue is very helpful and accentuates the sun flare.

As said above the sky is to white but saying that it's a very nice photo

I like the sun flare very much! And the scene with the people relaxing below invites the viewer to imagine being there. Perhaps cropping this to eliminate most of the sky would work well...and maybe taking some of the bright off the lawn. Nice pic.
