They look like they are having fun. That's a big plus and that's what I like best about the picture. There is so much happening, it's hard to find something to focus on. So, to improve it, I would try to find one or two elements and work with them. Get in close maybe, to cut some of the surroundings out.
I think this is a fun family shot. Lots of energy, clearly people are having fun. I'm not really fond of the action though, because it is all over the image and so my attention is jumping from one point to another erratically. Plus the action of it, makes portions blurred and because so many areas are blurred my attention then starts to wander. Had there been just one hula hooper, hulahooping, I think the balance wouldn't have tipped. Still it looks like a jumpin' time! 5
Sort of a busy image for me. I do like the motion blur and the expression on the blonde haired woman, but too many distracting things in the image, liek the orange parachute thingy at the top.
