Agreed, what the others said.
What stands out to me, that has been mentioned, is that depth of field. In those parking lot pics it goes back almost to infinity, seemingly. Makes me wonder if you're shooting w/ a point-and-shoot digicam? What are you shooting with?
You get nice puffy clouds in Florida, it'd be nice to polarize that sky...
Also, the only other problem I see is that you're taking pictures of Miatas...
