I've been working on this for a little while and I've decided I didn't like the pose of the boy at the shoreline.
I've been working from a digitized form of the photo and decided to go back and look at the original photograph which I had taken about a year ago.
I discovered a different photo of the scene I had ruled out and I like the image of the boy in the distance much better, so I'll be changing that figure.
There's a better sense of movement, and I like the fact that he's facing a different direction. One additional change I'll make is to put the green bucket in his other hand.
