I too, think the first and last are the best of your set. I like the action of the girl in the first one, especially with both feet off the ground. You caught her just right. The light you have in the last adds a lot of interest to the photo. Bright on the columns on the left and fading off somewhat to the right. The columns on the left and the columns on the right are exactly the same, but you can see a lot more detail in the columns on the left because of the way the light casts shadows on them. The light is also casting shadows off the children, giving an extra suggestion of movement. Try to imagine that shot with the same intensity of light like in your first photo and you'll see that it would be a lot less interesting.
