I like all the things to look at! Its a perfect comp Ami and even in B&W it looks great! I wonder what it looks like in color though. Excellent shot and work!
Busy is okay, I think, if you have a definite subject picked out as your point of interest, like the fountain, for example (which also is the darkest subject in the scene) and that point of focus is composed so that it falls at the point of two intersecting lines as in the rule of thirds. Like Raj, I think this would be more interesting, and perhaps less busy because there is probably a lot of green, in color. This is a lovely garden and your shot is so sharp and clear.
I don't know why, bit I see this as being a romantic place for older people..seniors..you know old codgers like me. If you know of any single, older women....tell them I will meet them in the park sometime in May. LOL. Gorgeous looking B&W, Ami.
