The color and the hazy blur invoke a sense of nostalgia - of a fond memory that has past. I like the sense of motion captured in the composition for it gives the viewer the feel of participating in the running play. I , I know, I am being very picky about details here, but as great as this is a capture of a carefree and playful day, it doesn't fully represent the nursery rhyme 100%. I see two girls at play, but no boys as the title says it should represent. I wonder if it was possible to pull back on the crop to include a little boy running off to the far right (a separate shot that would be integrated into the scene if necessary taking advantage of the Expert Editing option)
