Bynx, I really like the first shot.
However, I think even that shot's composition can be improved if you crop off some of the left portion, so that it's perfectly centered.
The large doorway on the left threw off my view of symetry when I looked through the viewfinder. Except if I have to rotate an image, I never crop. Any cropping is done when I take the shot. But I see what you mean and I like your crop.
Here are another couple pics.
