I think this shot would be better if you had focused in more on the people in the wheelchairs and not included the whole merry go round. just part of it. Also a larger size would have helped.
Rule #3 - Make your photograph as large as you possibly can. This is the 3rd biggest culprit for pictures doing poorly (#1 is out of focus, #2 is tilted horizons). The concept looks very good, its a shame about the size and the sunflare.
I love merry-go-rounds and hope I'll always be able to ride them. I can feel the yearning of this couple. I wish you had made the image a bit larger, and it seems a bit out of focus. But I like the composition here with the couple, facing away, at the side with most of the merry-go-round in the photo.
a little small, you probably have heard this but the file size here is max 640px on the longer side...
I'm not sure about the picture, looks like a snapshot to me... hard to see details though ...
there is a flare at the top, you should maybe watch out to point your lens not too much at the sun ; ) - you could though just hold your hand so that it blocks the sun from getting on your lenses glass...
