The first two posts are correct, the school is distracting, but they need to explain why. If the sprinkler is your subject, it needs to stand out from the background. In this case, there is not enough contrast in terms of hue and tone. The reds and pinks in the school are too similar to the reds and pinks in the sprinkler. Also, the tree trunks on the left are bright, and draw the eye to the left, and the hoses shoot the eye off to the right. Although such elements can make your image more dynamic, in this case, they direct energy and movement to the wrong areas.
Try taking the same shot in the evening with a fill flash. I think you'll get more desirable results.
