Blind window and Tree

For 10 years I have walked past this window with its stunted tree growing out of a crack. I've often thought it would make an interesting picture, but the window itself is about 12 feet off ground level and because of difficulty in framing it I kept on walking.

Today I finally took a picture. I'm not sure it worked very well. My wife thinks it looks like an aerial shot of an open grave.

Funny thing, in 10 years the tree doesn't appear to have grown. I suppose that means I've got plenty more time to get it right.
