I like how everything in the picture is a different shape and they all kind of act as puzzle pieces together. I would say that the only thing I don't like is the simplicity that I see, but it's a nice image regardless. This makes me feel like it was sort of a "discovery shot." What I mean is that you never have really looked at it like in the same way before, and it's interesting how it looks. It makes me think of a puzzle. For use of light, I personally might of waited for more shadows to emerge from the light source, which I assume is the sun. That might not of been the best option for you however, because you might not of been able to see all the shapes being made (also depending on which way the sun was moving). The composition is nice with the the left thirds being used, but I feel like there is a lot of empty space on the right. As far as processing, I feel like black and white was the best way to edit. Good work. --Kris
