Great shot.. High marks here. Archetecture/sculpture shots tend to go well with me anyway. Who are the figures that inhabit this scuplutre? I'm assuming Posidon is the center figure, who is on the sides? Perhaps Athena and Juno?
It is a very impressive fountain and you captured it quite well, though to be honest I think it could be lightened a little in a photo editor. The composition is pretty good and the level of detail is excellent. Where in the world is Trevi Fountain? Just curious.
