The best photos in this challenge, like yours, are in portrait layout, vertical, not horizontal. Cemetaries cause humans to look down then up. Lovely twilight setting to reveal the life beyond the grave.
I am making two passes on this Challenge. I will vote on your photo then return later(before voting is over) to comment on what I like and dislike about your shot. You can take the comments however you wish and I will try not to be mean. Just don't take it the wrong way.

You could have caught this at just the right time but the sky just looks too fake.
I really like the colors in the sky. The stone doesn't look as sharp as it could be and it has an odd color cast. Was it really this color? I think you may have done better with a more interesting headstone and not cropping it as tightly.
