On the question of "broad critique", I think the following makes a reasonable test:
Is this question likely to help other visitors with a similar situation? (Including, of course: might other people ever be in the same photographic situation.)
Will they be able to find it based on the title and description?
And, almost as important: will people with a totally different problem not be mislead into clicking on a question which doesn't even relate?
The last two are why I campaign so strongly against vague titles like this question's original title, which was "What could I do to take a better picture of this scene". But beyond that, if it's hard to find a title that's more specific, it's probably a sign that the question is too open.
In this case, it's on the edge in my mind, but it's my preference to be open to photography questions that are on the edge (and, a little less open to camera shopping questions). Of course, not everyone will agree with me.
In specific, the basic idea of a fountain with a backdrop seems likely to be something others will want to photograph. There are typical techniques for dealing with water, and the added twist of also wanting the context is both interesting and not too far-fetched.
(The question could certainly benefit from having some of the asker's comments edited into the question text itself, by the way.)
And if you want to post more questions which are a little more open in this way (while fitting the above), I'm okay with it. But, y'know... that's just one vote.
