Which image to submit?

There's a quarterly photo competition at work and I've entered a few times but never won. I want to enter one of the pictures below of a stream of water in some drainage pipe. Which do you like best? They're all very similar, but they have a few differences.

New kid pictures

The Natural Greenery behind the kids looks SO much better than the white sheet in the last pictures I took. So it was time for new pictures! After getting these shots, Erin and the kids played in the snow-melt stream that runs through the hollow we were taking pictures in. We even lost one of Josh's socks down the stream for a little while. Josh prayed for help finding it and then Erin found it. Prayers really are answered, even in eternally insignificant things.
