Please afford me the luxury of being a lone voice in praise of the differential focus on the trunks. I find it ideal in this instance.
I'm with Walter on this. The blurry trunks suggets motion, as if the trees are dancing in celebration (and tossing brightly-colored "confetti" in the air).
(And being a fan of the F/64 school, I seldom care for anything blurry in a photograph.)
