I'll take a shot at this. I'm going to make some assumptions below, so please correct me when I'm wrong... after all, making assumptions just makes an ass out of "u" (that would be me) and "mption", right?
Because I see a bit of sky peeking over the top stone wall in the upper left corner, I'm guessing that some limitation (you weren't allowed to get closer, for example) prevented you from framing this shot in the way you wanted. Or not. Was that done purposefully?
I'm also guessing that the repetition of the sign created by the lighter stone bottom left caught your eye, as did the slightly darker set of smaller stones mid right. You've arranged a triangle between these three elements.
Finally, you've in a way framed the upper edge of the sign with shadow, top left.
Overall, I think your idea has potential, but right now I'm not tasting the sauce, only its ingredients. What am I missing here?
