I chose one photo at random:
You have your aperture set at F/11. Why? It makes you use a long shutterspeed, hence the blur. You should make your aperture as large as possible (low fstop) if you're going to shoot action.
You have your ISO at 80. Why? You're shooting sports in bright sunlight; you should use 100 or 200.
You have your white balance set to tungston. Why? You're outdoors and there are no artifical lights. If you don't want your photos to be blue, use the correct white balance.
You have your exposure compensation set to -1. Why? You're going to get underexposed photos. Don't mess with your exposure compensation unless you're shooting in tricky lighting conditions or are trying to avoid blowing highlights.
You added a watermark. Why? NO ONE is going to steal your photos.
Why the heck is he doing a superman dive with a barrel cover on?
Learn more about photoshop than just brighten/contrast, crop, and watermarking. There's other stuff you could do that would make your photos less bad.
There was this book that came with your camera. The book is about a guy named Manuel. Manuel has all kinds of cool adventures. I highly recommend that you read about Manuel. Manuel will be able to help you get better photos.
