Cute kid. Looks like he found his foot

Over processed, IMO

Very nice, but a bit oversaturated

I'm not saying you did anything wrong as far as the rules are concerned.

What model camera are you using? Some oversaturate the colors on Auto...

The Canon T2i has a color oversaturation of about 111%, which can give you 'comic book' colors on Auto Mode. You will have to switch to a mode where you can make 'Picture Style' adjustments, and reduce your saturation slightly (-1 should bring to very close to a more natural color saturation). I believe you will find the information on or about Pg 92-94 of your user manual.

That's one of the joys of modern cameras, they allow for pretty easy 'point and shoot' capabilities, but have some very powerful tools built in to let you tweak the settings for even better photos.

Also, the Photography Contest rules DO allow you to make saturation adjustments with Photoshop so long as your adjustment (saturation) is applied to the entire image, and not just a portion of it (selective editing).

Hope this helps you, some!
