I rather like it, and can see why you liked it as well! Good job!
Can't wait to see the contrast of all the color values once it's converted to B&W!
The angle you picked for this shot works well and almost looks like it elongates the shadows. Nice shot!
I appreciate the various angles at which the benches and bricks present themselves against one another. The contrast in color between the bricks, benches and concrete are wonderful as well. Very strong image and wonderful perspective!
This is nice asymmetrical composition here, which accentuates those shadow shapes that interested you. With the strong, directional lighting you have here, there is a lot of potential for this image in black and white. I look forward to seeing what you come up with.
