The image certainly conveys silence but the content leaves a lot to be desired imo. It lacks balance, purpose and composition and therefore comes across as just a hastily taken snapshot. 5
Nice idea. First cemetary i've seen yet. I'd maybe work on the composition just a little (diff angle?) the little sign in the bottom is a bit distracting.
Your subject has the potential to invoke the desired feeling of silence, but the composition isn't very interesting as the empty space in the foreground is just a distraction.
