this looks like fun! From the photographic point of view, i would say get closer to one of the subject or shoot over someone's shoulder, but then again, your camera would probably get wet.
I like the twist on the word even in the sense of "getting even", yet you still kept an even number of people and buckets. Nice stopped action too, with the water splashing everywhere. Bet these boys had fun being your models!
Ha! excellent stop action! Great fun and those expressions are priceless! Takes me back to when I was a kid, having water fights with my friends in the summer. : )
(drifting off into reminiscent land now...)
I'm sure they had fun being your models. good job freezing the motion. mzy be next time you could control the background a bit more. It's too busy with tulips, a cat,... I caught myself trying to find more things in the background than watching the 2 boys in their water fight.
