Good symetry on pond. But for me it does not work well. The children are underexposed and we can't see their faces.

I think lower down catching their emotion would work. Or without children if you are trying to show the symetry.

If you're going for the symmetry, I would shoot with a wider angle, to catch more of the scene, assuming there is more interesting stuff outside of the current frame....

no there wasnt,I was using a tamron 28-75 on a 30d.
