There's just not enough to this image for me to give it much in a rating. Yep, I can tell the out of focus area is a key hole, but I really can't "see" what is beyond. So, as for framing something, the something seems missing. Maybe more focus to the foreground and a lens setting that provides more image in the background would help. Just my thoughts. Good luck.
This is a good idea, but the execution doesn't do very much for me. I think the viewer needs to see more of what is behind the keyhole, than the keyhole (and surrounding area) itself.
