I am a big fan of highly geometric (even abstract) shots, and yours is very close to that!I was about to edit it when I saw what RoyL did, which is close to what I would do. Some more straightening or slight perspective correction (to align the cross right down the middle of the frame, balanced on both sides) might make for a very bold composition.
But as always -- YOU know what YOU like, and if you know that, go right ahead and ignore me!
