Not a big fan of too wide of an angle here, but those indeed are good. The 3rd shot appears that maybe you were changing the focal length while taking the shot? And the last one is very sharp. That's my biggest problem with equipment right now is sharpness, it's even more of a problem I think than the limited aperture range with my cheapie camera.
And thanks for the votes. It's not a real photo contest unfortunately, basically just a popularity contest of who can beg more people to click for the vote, LOL. I do have not only family, but a collection of friends on some sim racing forum (if you call them friends, muhahaha) and folks on a photography forum clicking votes for me, hehe.
