Im currently in London right now on vacation with a few members of my family. Here are some of my better shots.

#2 is nice, but the horizon was centered. Better to go with the rule of thirds on something like this.

so a crop of either the the top or bottom half of the picture to even it into thirds would be better?

Well, you could do that. But it would be better to compose the shot in the viewfinder in thirds, before you take it. Or as in that bottom shot where it doesn't fill the whole frame, center the horizon then move the henge to the right third of the frame. In other scenes, or my favorites, shooting birds, an object that divides the frame diagonally like a stick the bird is perched on, or your first shot above, the red streak and the street, will more or less negate the rule of thirds. The only way to learn what looks good, [read acceptable] is to view a lot of other published images, magazines, books, online. I always look closely at the really popular photographs, to see what it is that makes them popular.
