I hate to be the bad guy but they just look like poor snap shots. I checked out your other post and It seems like your trying and thats why I just took some time to tell you what I see wrong and im no expert be any means. You need to work on your composition. They lack sharpness and photoshop cant help with that too much. Its best to get the sharpest photo from the start.
Get a book or HP website had a online class going for a while. you can even get tips from camera magazines websites. here is one I found with some videos http://www.digitalphotopro.com/in-motion/
once you get a good base of info then your photos will look much better and you will enjoy it more.
