I cannot really see the movement, but still relevant to the topic. i love the way you capture the activities and also a lot of empty space

hee hee...cute. I really like that you've included the stone wall too. I think it adds a point of interest. I just hope the kids stopped rolling before they hit it : )

excellent idea, and very cute capture.

Used to love to do this, great subject. I don't think your framing does it justice however. I think a much tighter framing would emphasize the subject better. The wall is distracting, if you had just the kids and the green grass, it would be better, IMHO.
