Thank you all, your comments have given me plenty to think about.
I think I might go with 'Deceptive Reflective Perspective" instead of 'Effective', particularly in view of your advice Toothy and also Tony's pointing out that there are relatively few straight lines in the pic. These are things that judges seem to like, by the way. (By the way Tony, you are quite correct; There is a tunnel to the right but it had too much extraneous clutter, including a crash barrier, to be included in the composition although I did take a separate picture of it which might be used at a later date.)
Regarding the titles, Con, the only real hard and fast rule is for wildlife which should only be called by its Latin scientific name to indicate that it is truly wild and not photographed in a zoo, for example. Other than that, most judges prefer titles to be fairly straight forward that explain what the picture is about if it is not too obvious from looking at it. The general rule seems to be keep it simple and to the point so I might just call number 3 "City Hall" or something similar.
Another thing to mention regarding the competitions is that it pays to enter three different subjects (e.g. 1 Landscape, 1 Wildlife, 1 Street) to maximize the chances of getting a decent score for at least one of them. While the majority of judges are impartial, it has happened that some have marked down photos for subjects or styles they have no taste for (which is why I was especially pleased to win the Panel Competition because the judge disliked the solarized style of photography that I had used).
