Thats not a bad camera, the issues will never be corrected until you learn the basics of shooting. You can have the best camera on the planet but if you dont understand how to use it as well as subject placement in the frame youll never improve. Like Insulin said, keep your horizon straight, those aggressive angles dont help the shots at all. Never have the inside of your tires facing out. Dont be afraid to move the car inbetween shots, you dont want to waste what could be a good shot because you had the wheels facing the wrong way. Spend some time learing how to adjust your camera/lens settings to get the most out of your shots. Once you learn the basics and how to adjust your settings then upgrade lenses, the better the lenses the better the shot outcome. Be prepared to spend money if youre serious about photography, its not a cheap hobby. If you really want better shots then youll have to buy better the lenses. The lower the Fstop the better the lens usually, youll want something at a length your comfortable with like 35 or 85, or a zoom lens like 17-50mm but youll always want something thats 2.8 or lower. Lenses with 1.8 or 1.4 or 1.2 will give you a great DOF for your shots and help draw attention to the subject.

I hope this helped.
