Fits The Challenge-Yes
Composition-Okay
Background-Okay
My Opinion-That sunshine!! I can not knock sun, since I live in Oregon and we praise and worship sunshine here. 'overexposed' I see from the comments below [including mine]you've got the idea. Also it was mentioned that reducing the aperture/raising the shutter speed/or adjusting the white balance can help correct the harsh lighting. It's a little dance and you either have too little or too much. Just have to keep shooting/playing with you camera and shoot tons of pictures. Good effort, keep going keep coming up with your own unique ideas. This shot has great texture.
This could be a potentially interesting shot. You have an interesting color contrast between the orange mesh, green grass, and white post. The critical problem is in the lighting. Because the light is so harsh, it is washing out the colors. I would suggest either using a polorizing filter or shooting with different light.
a little too bright. i think neither the orange and green are really allowed to add as much color punch to the photo as they could have - and more green could have been added by pulling back a bit or coming in and showing the green through the net in greater detail.
