I also like it but feel it benefits from a slight crop from the right - there's a lot of space there, some of which is needed to maintain the graphic nature of the image, but as is I think there's just a little too much. Well seen, though, and I like how you included the bit of wall crumble on the left - those small intrusions into a frame usually offset the balance of the image, but in this case, anchors it and keeps the image space defined.
