Just an interesting angle on the seats alone would have made a photographically interesting picture and would have allowed the viewer to imagine what sport was being played. For me, showing the field adds clutter to the picture and makes it just a snapshot.
Nice, clean colors. I think there might be a better composition for the shot that would bring you into a more focused interest. I probably would have straightened, but maybe you did and this made a more interesting take.
The goal in the foreground feels awkward, but I like the pattern of the blue seats broken up by the white ones. I think with a little composition tweaking this could be a very nice image.
