This is an interesting shot. It was a good concept, but the aren't a whole lot of right angles in the shadow, which happens to be the main focus. Speaking of focus, I'm sure you know by now that this picture is a little out of focus. Oddly enough it's a little grainy too.
nearly abstract, if not for the reality of the bricks. Poetic qualities to this image emphasized by the title. Very good shot and interesting point of view.
The idea is great and I like the composition, but the bricks on the left could do with a little more sharpness, the black spot is a little distracting, and there is quite a bit of noise in the image. Although not technically perfect, the composition and interest is good.
