Meets challenge well. The bucket in the center distracts the eyes and pulls all the attention to it. The benches on the right, and the rail of the stairs going down to the field on the right, also are distractions that interrupt the horizontal flow the repeating patterns had created.
Oh, oh, oh! Or is that ooohhhh? :D I say that because have you taken a look at how this image comes across with the top cropped at the edge of the grass!!! Some very nice color in this and I like the repeating lines. Get rid of the distractions up top and you've moved your score up at least 1-1.5 points, maybe more. JMO of course. Best of luck to you in the challenge.
What annoys me is that on a picture where horizontals and verticals play such an important role, the verticals aren't straight and off-center :(
Also, the bucket is distracting. If it were off-center and fallen over, it would instead have emphasized the emptyness I think.
Beautiful color banding though.
