It looks like there wasn't enough light for this shot, so it ends up with a dark haze over the whole thing that mutes all the colors and contributes to a drab feeling on the whole. The crowd, which you apparently intended to be central to the shot, need to be in better focus with more detail as well. A neat idea for a shot, and pretty well composed, but the execution suffers here quite a bit.
For a scrapbook photo or something your photo album this picture is fine, but to enter it in a photo challenge? It's a blurry shot of a quad (if the blur is intentional it isn't working for me) on flat ground. It's not interesting, exciting, or pleasing to the eye.
I dont really think this fits the challenge. It would go better in the 'Action Shot' challenge in my opinion. The colours also look a bit dull, which Auto Levels could possibly have fixed.
