I would have titled this with something to do with the unusual dimentions of the door. Something with some humor about it would be good for instance, "basket ball players entrance."
Otherwise, good use of black and white. The image is a little out of level looking.
Decayed, yes, but not enough to make it memorable. And the photo has been cropped too much. Seeing the whole of the door frame may have enhanced the effect. I can see jaggies on my screen - along the piece directly above the door.
Interesting entrance/door. This seems flat, like it needs more contrast and an exposure adjusment. Did you mess around with curves/levels some on this? Just a thought. Good luck in the challenge.
