The pictures are pretty good. But you should set the FOV down. Now it is a VERYY wide viewing angle. Sometimes a wide viewing angle is good but if you just do some normal pictures you should set it down.
No odd unnecessary angling. No void places generally. Wide angle lens is something special (avoid it for ever). Near plane and far plane together is good (you have it in great fire scene (only one I like). Narrow DOF is usially bad for wide angle and for regular car scenes. Use it to accent to main subject from environment. Feel the scenery!
